Jeremy Corbyn, the former leader of the UK Labour Party who was expelled due to allegations of antisemitism, is currently assisting Zohran Mamdani in solidifying his influence in New York City as of Sunday.

Mamdani’s collaboration with Corbyn emerges just days before the New York City mayoral election, where Mamdani is positioned as the progressive contender against the Democratic incumbent.

Mamdani, known for his vocal criticism of Israel’s military operations in Gaza and his association with the Democratic Socialists of America (DSA), has, like Corbyn, faced accusations of antisemitism.

Corbyn, now serving as an independent Member of Parliament, expressed his endorsement for Mamdani on Sunday through a Facebook post, featuring a photo of himself holding a “North London 4 Zohran” shirt.

“Let’s push Zohran past the finish line for a New York that is affordable for everyone!” read Corbyn’s post.

“Corbyn supporting Mamdani. What a surprise.” commented one social user. “Why are you interfering with influencing politics in New York?” asked another.

Corbyn also shared a phone-banking link which leads a website organized by the DSA’s NYC chapter which is urging volunteers to mobilize voters for Mamdani.

“Join NYC-DSA and Jeremy Corbyn, former leader of the UK’s Labour Party, as we call New Yorkers to get out the vote for Zohran Mamdani for mayor. We’re just two days from election day, and every conversation pushes us closer to winning a better New York,” the website reads.

Corbyn’s well-documented history with antisemitism allegations runs back to 2020 when the UK’s Equality and Human Rights Commission (EHRC) found that the Labour Party under his leadership had committed unlawful acts of discrimination against Jewish members.

Corbyn was suspended and formally expelled from the Labour Party in 2024 because of his response to the report. He has since launched a new left-wing political party called “Your Party,” and continues to deny all allegations of antisemitism.

Reacting to the collaboration, former New York Governor and mayoral candidate Andrew Cuomo quickly condemned Mamdani’s decision, writing on X.

“Having Jeremy Corbyn — someone whose party was found to have committed unlawful acts of discrimination against Jewish people under his leadership – phone-banking for @ZohranKMamdani says everything you need to know.

NY doesn’t need politics of moral compromise. We need leadership that rejects antisemitism, extremism, and division in every form and in every corner,” he wrote.

Meanwhile, a week before the election, a campaign finance watchdog group, the Coolidge Reagan Foundation, filed two criminal referrals against Mamdani, claiming he received illegal contributions from foreign donors.

The Mamdani campaign maintains that any issue regarding financial contributions has been resolved.
