Donald Trump’s presidential campaign has accused Sir Keir Starmer’s “far-left” Labour Party of interfering in the US election.

The Trump-Vance campaign filed a complaint with the US Federal Election Commission (FEC) accusing Labour of illegal foreign campaign donations.

In a statement, the campaign’s co-manager Susie Wiles campaign claimed: “The far-left Labour Party has inspired Kamala’s dangerously liberal policies and rhetoric.

“In recent weeks, they have recruited and sent party members to campaign for Kamala in critical battleground states, attempting to influence our election.”

The complaint referenced a Washington Post report that suggested “strategists linked to Britain’s Labour Party have been offering advice to Kamala Harris about how to earn back disaffected voters and run a winning campaign from the center left”.

It also mentioned a Daily Telegraph report that suggested Morgan McSweeney, Sir Keir Starmer’s chief of staff, and Matthew Doyle, his director of communications, “attended a convention in Chicago and met with Ms Harris’s campaign team”.

The complaint also cited a now deleted LinkedIn post from Sofia Patel, head of operations at the Labour party, who wrote that “nearly 100” current and former Labour party staff would be travelling to the US to help elect Ms Harris.

Mr Trump’s lawyers argue such support amounts to “contributions” from foreign actors, in violation of US campaign finance laws.
