Donald Trump has snubbed Keir Starmer by not inviting him to his inauguration because he “undermined” the US election, Elon Musk suggested.

The President-elect broke centuries of precedent when he invited world leaders to attend next week’s historic swearing-in ceremony.

Italian Prime Minister Georgia Meloni, Argentinian President Javier Milei, El Salvador President Nayib Bukele and Hungarian President Viktor Orban have all been invited to the showpiece event on January 20.

Reform UK leader Nigel Farage, a friend of Trump, is among a number of high profile rightwing politicians to have received an invitation, including Jair Bolsonaro, the former President of Brazil.

But Sir Keir won’t be attending next Monday with a visit to the White House more likely in the coming weeks.

The PM joins Vladimir Putin, Kim Jong Un and EU President Ursula von der Leyen on the list of leaders not to have been given an invite.

And Musk believes Labour “interferance” in the run-up to November’s US election has played a part in the Prime Minister’s absence from the Washington extravaganza.

The Trump campaign filed a complaint with the Federal Election Commission into alleged “blatant foreign interference” after it emerged up to 100 Labour Party staff campaigned in the US for Democrat candidate Kamala Harris.

Morgan McSweeney, the prime minister’s chief of staff, and Matthew Doyle, Downing Street director of communications, were both named in the complaint.

In a social media post on X, Musk suggested this was the real reason as to why Sir Keir had not been invited.

Musk was responding to a post by @Ikennect who questioned why the PM hadn’t been invited to the inauguration when 12 other world leaders had and what this does to UK-US relations.

“He sent operatives to America to undermine the US election!”, Musk wrote.
