LONDON (AP) — British Prime Minister Keir Starmer is facing a career-defining decision: step down or fight a challenge from Labour Party rival Andy Burnham.
Starmer has publicly vowed to stay in post, but pressure is building as more and more Labour Party colleagues conclude his time is up. Expectation is growing that he will announce a timetable for his resignation as soon as Monday. That’s the day Burnham will be sworn in as a lawmaker in the House of Commons after winning a special election last week.

Business Secretary Peter Kyle said Sunday that Starmer is “making time to reflect on the political realities, challenges and opportunities that he finds himself in.”
“I know he is a prime minister who always puts his country first,” Kyle told the BBC, though he said reports that Starmer will resign are “speculation.”
Starmer is spending the weekend at Chequers, the country mansion used by British prime ministers, with his family. He gave no public hint about his decision, but sent a Father's Day message on social media.
“Being a dad is my greatest joy. Today, I’m thinking about my dad, and the father I am to my children because of him,” he wrote on X.
If Starmer quits, he will be the sixth prime minister to leave office in the past 10 years, an extraordinary rate of churn for the United Kingdom.
Discontent with the prime minister has been building for months, with Labour lawmakers desperate to reverse the government’s decline in popularity since Starmer led the center-left party to a landslide election victory in July 2024.
He has struggled to deliver promised economic growth, repair tattered public services and ease the cost of living, and has been hamstrung by repeated missteps, including his decision to appoint Peter Mandelson, a scandal-tarnished friend of Jeffrey Epstein, as the U.K. ambassador to the United States.
Labour is losing liberal voters to the growing Green Party and facing a rising Reform UK, the Nigel Farage -led anti-immigration party that consistently leads in nationwide opinion polls.
Burnham, until this week the popular mayor of Greater Manchester, decisively won the seat of Makerfield in northwestern England in a special election held Thursday. He took almost 55% of the 45,510 votes cast, over 9,000 more than the Reform UK runner-up.
Now that he is a lawmaker, he’s in a position to challenge Starmer for leadership of the Labour Party. Burnham’s acceptance speech left no doubt that he wants to lead both the party and the country.
“Everyone knows that politics isn’t working,” he said. “Everyone can feel that the country isn’t where it should be. Tonight could, just could, be the turning point.”
It’s unclear whether Burnham would face a coronation or a challenge if Starmer steps aside. Wes Streeting, who resigned as health secretary last month to protest Starmer’s leadership, has said he will run in a contest if there is one.
Starmer congratulated Burnham on Friday, but insisted he would fight any attempt to oust him.
“I will run, I will stand,” if there is a Labour leadership contest, Starmer said. “I’ve said repeatedly I’m not going to walk away from that.”
But Charlie Falconer, a senior Labour member of the House of Lords, said Saturday that Starmer has “absolutely no authority” left.
“There should be an agreed transition process in which Andy and Keir cooperate as to when the handover should take place,” he told the BBC.

OBBUERGEN, Switzerland (AP) — U.S. Vice President JD Vance and senior Iranian officials arrived in Switzerland on Sunday to formally launch negotiations over Tehran’s nuclear program and build out the fragile interim deal to end the war in Iran.
The framework was signed last week, and now top U.S. and Iranian negotiators are in a 60-day sprint to reach an agreement on the technical details that hold massive implications for the world economy and global security.
Yet only days after signing the agreement, it’s being stress-tested after fighting escalated in Lebanon between Israel and the Iranian-backed militant group Hezbollah — and by the subsequent announcement by Iran’s military that it had closed the Strait of Hormuz, the vital waterway that transits a fifth of the world’s traded oil and natural gas.
Vance had originally been slated to be on the ground at the picturesque Bürgenstock resort near Lucerne on Friday, but his departure from the United States was delayed after fighting escalated in Lebanon and Iranian officials canceled plans to attend the talks.
Delegations from the U.S. and Iran, as well as mediators Pakistan and Qatar, arrived at the picturesque mountainside resort near Lake Lucerne on Sunday morning. Talks were expected to begin soon, according to the Swiss government.
U.S. Central Command disputed Iran’s claim that it had once again shuttered the strait and said U.S. forces continued to monitor the situation to ensure traffic continues to flow through the waterway. Vance has said that millions of barrels of oil have moved through the strait in recent days.
Vance departed the U.S. just after Iranian state TV said Iran’s negotiators had arrived in Switzerland. Tehran’s negotiators include parliamentary speaker Mohammad Bagher Qalibaf and Foreign Minister Abbas Araghchi, along with central bank and oil officials.
The U.S. vice president joins special envoy Steve Witkoff and Jared Kushner, President Donald Trump's son-in-law, who have already been on the ground to begin sifting through the technical details of the nuclear talks.
The talks between the U.S. and Iran will also include Pakistani Prime Minister Shehbaz Sharif and army chief Field Marshal Asim Munir, as well as Qatari mediators. Pakistan’s Ministry of Foreign Affairs said Sharif will also meet separately with each delegation from Iran, Switzerland and the U.S. “to reaffirm Pakistan’s enduring commitment to dialogue and durable peace in the region.”
Vance and his wife, second lady Usha Vance, arrived at Emmen Air Base outside Lucerne just before 6 a.m. local time, according to his office.
While Vance said he planned to be in Switzerland for just “a day or two,” leaving much of the detailed negotiations to be spearheaded by Witkoff and Kushner, his role in the talks has heightened scrutiny of the vice president at a time when he’s actively considering a 2028 presidential campaign.
Trump and Vance have come under searing criticism from parts of their own party for the deal, with Republican hard-liners unfavorably likening it to a nuclear agreement signed by the Obama administration that Trump and the GOP have insisted did nothing to actually terminate Iran’s nuclear program.
The agreement signed by Trump and Iranian President Masoud Pezeshkian immediately allows Tehran to sell its oil freely and paves the way for Iran to tap into billions of dollars in assets that are currently frozen. It also calls for Iran to dilute its stockpile of highly enriched uranium, believed to be buried under nuclear sites that were targeted in U.S. strikes last summer.
The agreement says commercial vessels can pass through the Strait of Hormuz for 60 days without a charge, but does not preclude future fees imposed by Iran. Trump made his own threat on Saturday to levy U.S. tolls on the strait if there is no deal with Iran in 60 days, insisting in a social media post that the money would be for “services rendered as the Guardian Angel to the countries of the Middle East.”
The Trump administration has been working to reassure global markets that the Iran war has been merely a blip on oil prices, as Americans have complained the conflict resulted in hiking gasoline prices ahead of peak summer travel months. After the White House announced the deal a week ago, oil futures dropped almost 8% — and markets are expected to closely track the progress of talks when they open for trading on Sunday evening.
Further complicating matters, neither Israel nor Hezbollah is a signatory to the deal between the U.S. and Iran, and Israeli Prime Minister Benjamin Netanyahu has vowed to keep his forces in southern Lebanon until any threat to Israel is eliminated. Hezbollah has refused to halt its attacks unless Israel commits to withdrawing from Lebanon.
Fighting between Israel and Hezbollah in the initial days after the agreement between the U.S. and Iran killed 47 people in Lebanon, as well as four Israeli soldiers.
