LONDON — Britain set itself on course for a new confrontation with the European Union on Tuesday by demanding the replacement of one of the most complex and vexing components of Brexit: the status of Northern Ireland.
In a speech to diplomats in Lisbon, David Frost, the Conservative government’s Brexit minister, asked for an overhaul of an agreement on post-Brexit trade rules for Northern Ireland, which is part of the United Kingdom but shares a politically sensitive land border with Ireland, a European Union country.
The move is a serious escalation in a simmering dispute over how Northern Ireland fits into the British withdrawal from the European Union. Mr. Frost’s proposed new text for the trade rules, called the Northern Ireland protocol, discards some elements that Prime Minister Boris Johnson agreed to less than two years ago and contains ideas the European Union has already rejected.
“We now face a very serious situation — the protocol is not working,” Mr. Frost said, arguing that instead of protecting a fragile peace process in Northern Ireland, the agreement was doing the opposite.
“The protocol represents a moment of E.U. overreach, when the U.K.’s negotiating hand was tied, and therefore cannot reasonably last in its current form,” Mr. Frost said, adding that it had been drawn up in extreme haste and that for the Europeans to reject the idea of changing it “would be a historic misjudgment.”
His speech served as something of a pre-emptive strike, coming just one day before the European Commission, the bloc’s executive body, is scheduled to present its own plans to resolve the difficulties it acknowledges have arisen with trade mainly between Britain and Northern Ireland.
Though soft-spoken and personable, Mr. Frost is a hard-liner whose aggressive negotiating style has been welcomed by Brexit supporters who believed that Mr. Johnson’s predecessor, Theresa May, was pushed around by Brussels. So, few were surprised that his speech raised the temperature on an inflammatory issue.
But significantly, Mr. Frost also called for a change to the role of Europe’s top court in adjudicating disputes — an abstract but politically sensitive issue over which the European Union is highly unlikely to concede.
That has prompted speculation that the demand is a bargaining chip to be traded for other concessions. An alternative theory is that it is designed to provoke a full-scale crisis that could lead to Mr. Johnson suspending part of the protocol, blaming the European Union and stoking pro-Brexit sentiment at home.
That would likely prompt retaliation from the European Union and possibly a trade war with the 27-nation bloc that Britain officially left in January 2020.
Designed to avoid resurrecting a hard border between Northern Ireland and Ireland, the protocol has led to checks on goods flowing from Britain to Northern Ireland.
That is to protect the integrity of the European Union’s giant single market of which Ireland is a part. But it has infuriated unionists in Northern Ireland who see their place within the United Kingdom as central to their identity and who resent checks on goods flowing from mainland Britain, which is part of the same country.
Mr. Johnson has the ability to suspend parts of the protocol under Article 16 of the Brexit agreement, but he is considered unlikely to do so before the climate summit, COP26, Britain is hosting in Glasgow from Oct. 31 through Nov. 12.
Discarding some of the protocol could also exacerbate tensions between Mr. Johnson and President Biden. The American president is proud of his Irish heritage and has made clear his commitment to the peace process in Northern Ireland that culminated in the Good Friday Agreement, struck in 1998 after decades of bloody conflict known as “The Troubles.”
Though some analysts believe Mr. Johnson wants to walk away from the protocol to please Brexit hard-liners at home, others see Tuesday’s speech by Mr. Frost more as a tactical intervention designed to minimize the influence of Brussels over any part of Britain, and maximize British sovereignty.
“Frost — who is a convinced Brexiteer — sees this attempt to renegotiate or adjust the protocol as the final means to weaken the ties that remain between the U.K. and the E.U.,” said Katy Hayward, a professor of political sociology at Queen’s University, Belfast.
Britain, she added, seemed to be “trying to wrangle the last bits of sovereignty from the E.U.”
Tuesday’s speech follows months of tension over impediments to trade between Britain and Northern Ireland, including the flow of some goods like chilled meats, a rift that became known as the “sausage wars.” In recent days that gave way to open sniping during which the Irish foreign minister, Simon Coveney, questioned whether Britain actually wanted an agreement, and Mr. Frost accused his European counterparts of refusing to listen.
Britain argues that the protocol is being implemented in an unnecessarily heavy handed way, while European officials accuse Mr. Johnson of breaking an agreement he made himself.
Answering questions after his address on Tuesday, Mr. Frost said that when Britain agreed to the protocol, it knew it was taking a risk. “We hoped that we were wrong and that the protocol would work,” he said. “It turned out we were right.”
For its part the European Union has repeatedly rejected Britain’s calls for a renegotiation of the agreement. It particularly opposes the removal of the Court of Justice of the European Union, based in Luxembourg and the bloc’s highest court, as the final arbiter of disputes.
Responding on Monday to excerpts from the speech that were released on Saturday for the British media, the spokesman for the E.U. Commission, Eric Mamer, described London’s demand to remove the court as unacceptable and “ground that we have covered a million times.”
Brussels often emphasizes that this British government signed the deal, which Mr. Frost himself negotiated, and which is now international law.
Another commission spokesman, Daniel Ferrie, said that oversight of European courts was essential to provide legal coherence and a functioning business environment throughout the single market.
Removing the court, Mr. Ferrie said, “would effectively mean cutting Northern Ireland off from the E.U.’s single market and related opportunities.”
On Wednesday, the commission will make proposals to smooth implementation of the protocol. Those measures are expected to include easing of food and plant safety checks to soften restrictions on trade in chilled meat from Britain into Northern Ireland. It may also ease some customs checks and checks on the supply of medicines.
The commission will also propose some ideas on how to engage citizens, business owners and politicians from Northern Ireland in oversight of the deal.
But Mr. Frost’s intervention suggests that such concessions will hardly be sufficient, setting the scene for several weeks of tense negotiation.
Ms. Hayward said that the risk for Northern Ireland was that Mr. Frost’s approach would do little to reassure the unionist community about the security of their place in the United Kingdom, while raising unrealistic expectations about the prospects of a completely new agreement.
“If you were to prioritize the peace process above all else when you are approaching the matter of the protocol and talks with the E.U., you wouldn’t go about it the way the British government has gone about it,” she added.

Police Search for Motive in British Lawmaker’s Killing
LONDON — The police searched for answers on Sunday about what might have motivated a 25-year-old British man of Somali heritage, the suspect in the brutal slaying of a Conservative Party lawmaker during a meeting with his constituents that has shaken Britain’s political establishment.
Scotland Yard has not yet publicly named the suspect, though British news organizations, including the BBC, have identified him as Ali Harbi Ali. Mr. Ali’s father, Harbi Ali Kullane, told The Times of London that his son was being held in custody and described himself as “very traumatized” by the accusations.
Referring to the accusations, Mr. Kullane, who once served as an adviser to Somalia’s prime minister, said in the interview with The Times, “It’s not something that I expected or even dreamt of.”
The BBC reported that several years ago, Mr. Ali had been referred to a government program known as Prevent, which aims to keep people from being drawn to extremist ideas on social media. But his name has not been on any terrorism watch lists, according to the broadcaster.
The Metropolitan Police said on Saturday that they had been granted a warrant under the Terrorism Act to keep the suspect in detention for six extra days in connection with the killing of the lawmaker, David Amess, on Friday in Leigh-on-Sea, England.
On Sunday, the police guarded a red-brick rowhouse on a tree-lined street in North London where the suspect is believed to live with his family. It was one of three addresses in London that were being searched by the police.
A next-door neighbor, Tilly Gerrard, said three young men and a woman lived in the second-floor apartment. She described them as a neighborly presence in a community where most residents recognize one another and that recently threw a street party.
Counterterrorism experts said the attack on Friday differed from those in that, according to news reports, the assailant did not harm anyone else in the room, waited for the police to arrive and arrest him, and made no attempt to confront the officers.
“It doesn’t feel like anything we have seen before,” said David Videcette, a former counterterrorism detective at Scotland Yard.
Under the terms of the Prevent program, teachers, health workers and others can notify the police of potentially radicalized individuals, and the authorities then decide whether to intervene. The program is voluntary and does not result in a legal record.
Political leaders expressed outrage about the attack but insisted that it should not endanger a tradition of accessibility and face-to-face contact with members of Parliament that is deeply ingrained in Britain’s political system.
“This is an attack on democracy,” Gordon Brown, a former prime minister, said Sunday in an interview on Sky News, “so the answer cannot be less democracy.”
Still, the killing, at midday and in full public view, has rekindled questions about the security of members of Parliament, who routinely make themselves available to constituents in monthly meetings that are advertised in advance and that can become tense when voters show up with lists of grievances.
Two other lawmakers have been attacked at such meetings in little more than a decade. One, Jo Cox, a Labour Party lawmaker, died after she was stabbed and shot by a right-wing extremist a few days before the Brexit referendum in 2016. The other, Stephen Timms, also a Labour lawmaker, was seriously wounded after being stabbed in the abdomen by an Islamic extremist in 2010.
Britain’s home secretary, Priti Patel, said the government would review security policies for lawmakers, particularly as they relate to constituent meetings, known as surgeries. But she cautioned that these measures should not prevent voters from having face-to-face access to their elected representatives.
“We’re here to serve — we’re here to be accessible to the British public,” Ms. Patel said in an interview with the BBC.
Members of the public are usually asked to sign up in advance to attend surgeries, and news reports said the suspect had done so before Friday’s meeting, which was held in a Methodist church in Leigh-on-Sea.
In an interview with Sky News, Ms. Patel said the government would also consider tightening laws on social media to cut down on abusive behavior, including by removing the right of people to post material anonymously.
In the neighborhood where the suspect is believed to live, residents expressed bewilderment about why someone would target a lawmaker in a town 40 miles away. A man passing on the street said that his younger brother had attended primary school with the suspect and that he was shocked to hear the reports.
The motive for targeting Mr. Amess, who was 69, was not clear. A soft-spoken, well-liked backbencher in the House of Commons, he was known for his staunch support of Brexit and his advocacy for animal rights.
A Catholic and social conservative, Mr. Amess was also a strong supporter of Israel and of an Iranian opposition group, Mujahedeen Khalq, or M.E.K., which campaigns for the overthrow of Iran’s government.
In London’s close-knit Somali community, reports of the attack stirred shock and unease, with some people voicing anxiety about a backlash. Though many Somali immigrants were displaced in the 1990s by the country’s civil war, the roots of the community in Britain go back generations.
“It’s very much people that are born here, and raised here,” said Kahiye Alim, the director of the Council of Somali Organizations, an umbrella group.
Tunisians Recall Revolution Reluctantly, if at All: ‘It Just Faded Away’
LE KRAM, Tunisia — When part of one of Tunisia’s only monuments to its 2011 revolution disappeared earlier this year, not many noticed.
Some residents of Le Kram, a suburb of the capital, Tunis, say the plaque bearing the names of eight locals killed while protesting was broken off by someone with a mental illness. Others say a passing drunk was to blame.
Whatever happened, the real story is that no one bothered to fix it.
“This place wasn’t maintained, as you can see,” said Aymen Tahari, 40, the owner of the struggling plant nursery facing the monument and, as of about two weeks ago, its self-appointed caretaker. “During the first year after the revolution, there was a kind of support from everyone, but then it just faded away.”
A decade later, Tunisia remembers its uprising — which ignited the region-upending protests that came to be known as the Arab Spring, overthrew a dictator and ushered in the movement’s only remaining democracy — with a kind of reluctance bordering on hostility, the euphoria of that time stanched long ago.
This Jan. 14, the 10-year anniversary of the day the dictator, Zine el-Abidine Ben Ali, fled the country, there was no official tribute, only more protests over Tunisia’s no-end-in-sight economic decline.
More than remembrance, there is regret.
The revolution answered few, if any, of the hopes it raised for economic opportunity, accountability and an end to corruption, many Tunisians now say. This decade of disappointment with their elected leaders is why many Tunisians supported the events of this July, when President Kais Saied sidelined Parliament and seized power, precipitating a political crisis that still grips the country.
“The revolution is history now,” Mr. Tahari said. “Now we’re moving forward.”
In 2019, Le Kram’s mayor tried to immortalize its part in that history, choosing for the site of the memorial to those killed a roundabout ringed by a half-empty cafe, the shell of a parking garage, a car dealership and a stand hawking cheap handbags. In the middle of the roundabout is a scraggle of dried-out grass, and in the middle of the grass stands a black metal spike, the Tunisian flag flying crisply from its tip.
On a recent morning, Mr. Tahari was pacing the roundabout with one of his workers from the nursery, discussing plans to pick up the cigarette butts and water the grass.
Nobody had asked him to. But the municipality lacked the money, everybody else lacked the will, and he thought it would be a nice thing to do. He said he had not given much thought to honoring the martyrs, as Tunisians call them.
Not that he was diminishing their sacrifice. Back in 2011, he said, Ben Ali’s repression and corruption made the revolution unavoidable and bloodshed inevitable.
Officials have said such memorials had to wait for a government-approved list of the dead and wounded, which was not published until this March after a decade of pleas from the victims’ families, quarrels over who constituted a “martyr” and charges that old-regime sympathizers were obstructing the work.
What few tributes exist are put up by local governments or, often, by families at their own expense.
“We had no interest in the details of the official list,” Fathi Laayouni, the mayor of Le Kram, told an interviewer last year. “We know our martyrs very well, and we took the initiative to soothe the pain and suffering of the families.”
The memory of the revolution is constantly contested.
Tunisia’s post-revolution Truth and Dignity Commission spent years collecting evidence of crimes committed under Ben Ali and his predecessor, Habib Bourguiba, only to run into obstacles to prosecuting the perpetrators. After being removed in 2011, a statue of Bourguiba triumphant atop a horse returned in 2016 to his namesake avenue in downtown Tunis, the same street where thousands of Tunisians had chanted for Ben Ali to “Leave!”
Walking down the avenue, no one would guess that the square near the statue is supposed to be called the 14 January 2011 Square. There is no sign.
It would be easy to blame old-regime sympathizers in power. But many Tunisians have far more nostalgia for their ex-dictator than the revolution that toppled him.
If Ben Ali had kept ruling as he did in his early years in charge, “he could’ve stayed,” said Sondes Kouni, 55, from the coastal city of Sfax, who was walking through the Le Kram roundabout. She had not protested in 2011, but had, in the end, been persuaded that Ben Ali needed to go.
Those who were killed protesting “didn’t die for nothing,” she added. “But afterward, there were mistakes that weren’t supposed to happen.”
According to Mr. Tahari and many others, Tunisia’s post-revolution leaders had done next to nothing other than enrich themselves and their friends.
Perhaps none have greater cause for bitterness than the families of the dead.
Le Kram’s black spike is not the only one of the neighborhood’s memorials to the killed; a simple block of marble was first put up by their families. Inscribed with the eight names, it stands across from its taller cousin in the roundabout.
The municipality holds quiet commemoration ceremonies at the big monument, but only the families come to the small one.
“We did it so that their names remain,” said Saida el-Sifi, 63, whose son Chokri el-Sifi, a gas station worker, was 19 when he was shot in the protests.
Adorned with at least a dozen photos of Chokri large and small, the family’s home is itself a monument of sorts to him. The family moved there after his death, claiming what had been state property, and hung a plaque outside the gate proudly announcing it as the home of a revolutionary martyr.
Despite government attempts at eviction, they have been living there ever since. Ms. El-Sifi considers it her right, having sacrificed her son for Tunisia. Now she expects Mr. Saied to fulfill government promises made to families then, and never kept: To put the shooters on trial and to compensate the survivors.
“I still support the revolution, but the last 10 years, it was a mess,” she said. “We really hope Kais Saied, now he’s president, will solve the problems and save the country and bring us our justice.”
Passing the roundabout on her way home, Arbia Jneihi, 46, often pauses over the name of her husband, Nouri Sikala, a carpenter shot while protesting on Jan. 13, 2011. He was 30.
“When I see his name, I go back in history, I go back in my memories,” she said. “We could’ve had a normal life, we could’ve had kids. But everything was just a dream.”
Mr. Sikala had protested because of all the official mistreatment he had endured, she said: roughing-up from police officers, insults at the town hall. Le Kram’s streets had been full of aggrieved people like him, burning down the police station, burning tires. In some places, you could still see the marks.
But Ms. Jneihi, who has a low-level government job — one of her few survivors’ benefits — said she had joined the revolution more “to go with the flow.”
It had brought her only regret.
“I wish he hadn’t gone out. I wish the revolution hadn’t happened. I was actually, at one point, wishing I hadn’t met him at all,” she said. “We had a hope, we had a dream, but it just stayed a dream.”
For all its failed promise, however, Mr. Tahari says he still believes in the uprising’s ideals.
“We showed,” he said, “that it’s the people who have the power.”
How a Stunning Lagoon in Spain Turned Into ‘Green Soup’
LA MANGA, Spain — The Mar Menor, a saltwater lagoon on the coast of southeastern Spain, was long renowned for its natural beauty, drawing tourists and retirees to its pristine warm shallows and the area’s gentle Mediterranean climate.
But over the past few years, the idyllic lagoon has come under threat. Tons of dead fish have washed ashore as the once-crystalline waters became choked with algae.
Scientists are divided over whether climate change — causing excessive heat that reduces oxygen levels in water — is contributing to the problem. But they agree that nitrate-filled runoffs from fertilizers from nearby farms have heavily damaged the waters where oysters and sea-horses used to thrive. But farmers in the area have balked at shouldering the blame.
Hugo Morán, a senior official in the central government’s environment ministry, estimated that 80 percent of the water contamination resulted from the unchecked growth of agriculture. He also put some of the blame on local politicians, accusing them of long downplaying the contamination and proposing unviable remedies, such as channeling plenty of the lagoon’s waters into the Mediterranean Sea.
This would only create another victim, he said.
“To heal, you first have to recognize the illness,” he said. “But what we have heard, instead, are sporadic claims by the regional government of Murcia that the Mar Menor is doing better than ever.”
Similar problems have cropped up in other parts of the world recently. Pollution, including from nitrogen-based contaminants, has been blamed for accelerating the secretion of a slimy substance called mucilage that has clogged the Sea of Marmara in Turkey. And waste produced by a nearby electricity plan and oil refinery has damaged the giant Berre lagoon in southern France.
The area around the Mar Menor, with its fertile fields and temperate year-round climate, has proved irresistible to large-scale farms, which often use ecologically damaging nitrate fertilizers. Adding to the problems, there has been extensive tourism development on the narrow, 13-mile sandbank known as La Manga, or the Sleeve, that separates the Mar Menor from the Mediterranean.
Whoever is to blame, María Victoria Sánchez-Bravo Solla, a retired schoolteacher, has had enough.
When five tons of dead fish washed up in August near her house on the lagoon, she decided that she was ready to move. She called it “an environmental disaster that should put our politicians and all those who deny responsibility for allowing this to happen to shame.”
Such mass die-offs of fish have happened a few times over the past five years, and the stench of decomposing algae, which has turned the lagoon’s waters darker and murkier, is a further sign of the ecological crisis.
Local restaurants no longer serve Mar Menor seafood and commercial fishing crews now trawl in the nearby Mediterranean instead. Few residents would even consider taking a dip in the lagoon anymore.
As the problems have intensified, so has the blame game.
The conservative administration of the Murcia region says the Spanish central government in Madrid, currently a left-wing coalition, should do more to help. Madrid says the responsibility lies at the local level.
Miriam Pérez, who is responsible for the Mar Menor in the regional government, said she believes political rivalries are keeping the central government from doing more.
“I unfortunately do think that political colors matter,” she said.
She said the central government had done little to support her right-wing administration’s cleanup efforts — including removing about 7,000 metric tonnes of biomass — mostly decomposing seaweed — even after the region issued a decree in 2019 to protect the lagoon.
In August, when another wave of dead fish washed up, scientists noted that the water temperature had climbed significantly. But in September, the Spanish Institute of Oceanography published a report that rejected the idea that excessive summer heat helped kill the fish.
Scientists instead place much of the blame with farming. In 1979, a canal was opened to carry water from the Tagus — the longest river in the Iberian Peninsula — to southeastern Spain. The canal led to irrigation, which transformed Murcia into one of Europe’s farming powerhouses, producing lettuce, broccoli, artichokes, melons and more for export across the continent.
Agriculture represents 8.5 percent of the region’s gross domestic product and provides about 47,000 jobs, according to a study published last year by the University of Alcalá, near Madrid.
But the farmers around the Mar Menor have deflected the blame, saying that the contamination comes from water seeping into the lagoon from an aquifer in which toxic substances have accumulated over decades.
Vicente Carrión, president of the local branch of COAG, an agriculture union, said that farmers were now strictly using only the amount of fertilizers needed for plants to grow.
“We are getting blamed for what went on 40 years ago” when less scrutiny was placed on agricultural practices and the authorities’ emphasis was on taking advantage of the demand from across Europe, he said.
Adolfo García, director of Camposeven, an agriculture exporter that harvests about 1,500 acres of land in the region, said that most farmers had already switched to sustainable production methods. Laggards should get government incentives to invest in green technology rather than “stones thrown by people who have no knowledge of our modern irrigation systems,” he added.
“Even if we planted nothing in this area for the next 50 years, the aquifer would remain very polluted,” he said.
But Julia Martínez, who grew up in the region and is now a biologist and technical director at Fundación Nueva Cultura del Agua, an institute that specializes in water sustainability, said that the arguments about the aquifer were a red herring. She said at least 75 percent of the lagoon’s water contamination came from runoffs.
The impact of tourism — another giant contributor to the local economy — is another problem. The Mar Menor’s hotels and restaurants are concentrated along the sandy bar of La Manga, where dozens of apartment blocks were also built, many as holiday homes. Almost every inch of the strip is developed.
Mr. Morán, the environment secretary, acknowledged that the Mar Menor had suffered from an “open bar” approach in terms of awarding building permits. But he mostly blamed fertilizer runoff from farms.
The lagoon was proof that “one of the major problems of Europe is the contamination of its waters by nitrates,” he said.
Pedro Luengo Michel, a biologist who works for Ecologistas en Acción, a Spanish environmental organization, said the farming and tourist industries have broad influence, particularly at the local level where the conservative Popular Party has governed since 1995.
“We are confronting a very powerful farming lobby which our politicians depend on to stay in power,” Mr. Luengo Michel said.
Mr. Morán said that his central government planned to use 300 million euros, or about $350 million, from the European Union’s pandemic recovery fund to protect the Mar Menor’s natural habitat and waters. The plan includes replanting vegetation close to the shores, which can stop contaminated water flowing in from neighboring fields.
For some scientists, monitoring the deterioration of the lagoon has felt like a personal tragedy.
“I remember finding it stunning as a child that I could see the sand at the bottom without even noticing the water because the Mar Menor was so transparent,” said Ms. Martínez, the biologist.
“Now, we sadly have a green soup and I certainly have long stopped swimming in it.”
