UK Prime Minister Keir Starmer, who resigned the premiership on Monday, leaves behind a mixed record on fighting antisemitism in the Labour Party that Jewish organizations say will help shape their expectations for his successor.

Starmer announced that he was stepping down outside 10 Downing Street on Monday morning. He made the decision in the wake of mounting pressure from Labour members of Parliament and waning political support after the party’s devastating losses in the May 7 local elections and the success of political rival Andy Burnham in Manchester’s parliamentary election last week. 

Burnham, the former mayor of Greater Manchester, has emerged as the leading contender after winning a Manchester-area by-election on Friday with 55% of the vote. Burnham has sought to position himself prominently on antisemitism and relations with the Jewish community in his bid to take over from Starmer.

In a post on X/Twitter, Burnham thanked Starmer for his leadership and said the PM’s decision to resign “marks the beginning of a transition and it is important that this process is conducted in an orderly and responsible way. I will put myself forward as part of this process.”

Starmer to remain in role until successor is chosen

Starmer confirmed he would remain on as caretaker prime minister until a successor was chosen.

“The question my party is asking now is whether I am best placed to lead us into the next general election,” he said. “I have heard the answer of my parliamentary party to that question, and I accept that answer with good grace.”

The Jewish Labour Movement thanked Starmer in a post on X/Twitter, noting that two years ago he inherited the party “at its lowest point” from former party leader Jeremy Corbyn, when it was “institutionally antisemitic.” It added, under Starmer, “our party has a clean bill of health on antisemitism.”

However, Starmer’s tenure was still met with plenty of criticism from the Jewish community over his handling of antisemitism, particularly in light of ongoing antisemitic attacks in the country. In recent months alone, four Hatzola ambulances were lit on fire; there were attempted attacks on three synagogues; two Jewish men in the Orthodox neighborhood of Golders Green were stabbed. Dozens of people have been arrested in connection with the incidents.

Starmer entered office in July 2024, leading his country’s thorny relationship with Israel in the aftermath of the Hamas October 7, 2023, attack against the Jewish and the Gaza war that followed. He angered Israel with steps such as recognizing Palestine as a state and promising to uphold the International Court of Justice’s arrest warrant against Prime Minister Benjamin Netanyahu for war crimes.

With Starmer’s upcoming departure, focus has shifted to the contest to replace him, bringing renewed scrutiny to candidates’ positions on antisemitism, relations with the Jewish community, and Israel.

Starmer said he would give his successor his “full and unequivocal support,” adding that nominations would open on July 9 and conclude before the parliamentary summer recess on July 16.

Board of Deputies of British Jews President Phil Roseneberg posted on X/Twitter, “When he took on the leadership of the Labour Party, the first thing @Keir_Starmer said he would do is ‘tear out the poison of antisemitism by its roots’. His subsequent actions were transformative within the Party.”

He praised Starmer’s government for providing “unprecedented security funding,” and introducing legislation to proscribe the IRGC.

Burnham spoke out against antisemitism, but scrutinized for stance on Israel

Burnham, for his part, has spoken out against antisemitism in the wake of violent attacks. Following the October 2025 Yom Kippur attack at the Heaton Park Congregation synagogue in Manchester, in which two people were killed, Burnham said in an official release, “Tonight, our first thoughts are with the families of those who have died, those injured and those traumatised by this – a horrific antisemitic attack on our Jewish friends and neighbours. We condemn it outright.”

He also wrote in a post on X/Twitter on the same day, “Today we have witnessed a vile attack on our Jewish community on its holiest day. We condemn whoever is responsible and will do everything within our power to keep people safe.”

His positions on Israel and Gaza have also come under scrutiny. In a June 4 interview with The Guardian, Burnham did not invoke the term “genocide” in relation to the war in Gaza, but did say, “I can’t judge things of that enormity from where I am as mayor of Greater Manchester.” 

He added, “But I do have concerns about the disproportionate nature of what has happened in terms of the destruction, and there has to be a full process of investigation and accountability.”

Additionally, 10 days after the October 7 attacks, Burnham called for a ceasefire in a joint statement with 10 Greater Manchester leaders. The statement read in part, “We condemn unreservedly the appalling terror attacks on innocent civilians in Israel by Hamas on 7th October.”

The statement also noted that Israel has the right to take “targeted action within international law” to defend itself and to rescue its hostages, but added, “We also have profound concerns about the loss of thousands of innocent lives in Gaza, the displacement of many more and widespread suffering through the ongoing blockade of essential goods and services.”

Referencing his expected leadership bid, Culture Secretary Lisa Nandy told the Jewish News on June 17 that Burnham had a few weeks earlier met with Jewish communal leaders in Greater Manchester.

When it comes to Israel, Nandy said Burnham “believes in justice, so he’s acutely aware of the need for a safe homeland for Jewish people, you know, and the particularly unique historical reasons why Israel came into existence.”
