Trump shares blunt verdict on UK Prime Minister Keir Starmer before making bold prediction

United States President Donald Trump has given his blunt verdict on United Kingdom Prime Minister Keir Starmer.

The 80-year-old Republican took to Truth Social on Sunday (21 June) to share a brief message about Starmer's impending resignation as PM, writing: "Keir Starmer will resign as Prime Minister of The United Kingdom."

Trump continued to claim: "He failed badly on two very important subjects - IMMIGRATION AND ENERGY (OPEN NORTH SEA OIL!)."

He concluded the social media post: "I wish him well! President DJT."

Trump has repeatedly criticised Starmer's stance on North Sea oil drilling, recently claiming Europe was 'desperate' for oil and blaming the UK for restricting supply because the 'United Kingdom refuses to open North Sea Oil'.

Last year, Trump also urged Starmer to deploy the military along Britain's coastline in order to deport migrants.

If Starmer were to resign today (22 June), Britain would be preparing for its seventh prime minister in a decade.

Andy Burnham, who recently returned to Parliament, is currently seen as the favourite to succeed him.

Meanwhile, former health secretary Wes Streeting has repeatedly insisted he has the 81 names required to mount a leadership bid, and has spent the weeks since his resignation setting out his stall.

And former Royal Marines officer Al Carns, who quit as armed forces minister in a row over defence funding and the treatment of Northern Ireland veterans, has also hinted he would seek to enter a leadership race, although it is unclear whether the MP – who was only elected in 2024 – has the supporters required to get on the ballot paper.

The UK must always have a Prime Minister, so if Starmer offered his resignation, he would probably remain in post until a replacement was chosen.

That replacement would be decided through a Labour leadership election, which is automatically triggered if the party leader steps down.

The contest happens in two stages.

First, Labour MPs put themselves forward as candidates. Labour MPs then vote through several rounds until only two contenders remain.

After that, Labour Party members vote to choose the next leader, and whoever wins will automatically become Prime Minister.

A new Prime Minister does not have to call a general election.

The next general election must legally happen by August 2029.

But the Prime Minister can choose to call one earlier, known as a snap election.
