United States President Donald Trump has predicted that British Prime Minister Keir Starmer will resign from office, launching a sharp critique against the UK leader’s handling of immigration and national energy security.
Trump made the controversial claims in a post on his Truth Social platform on Sunday, June 21, 2026, just as Starmer huddles with advisers at his Chequers country retreat to consider his political future amidst a mounting mutiny within his own governing Labour Party.
Linking Starmer’s fragile leadership standing to long-running policy disputes, Trump claimed the British leader has fallen short across critical sectors.
“Keir Starmer will resign as Prime Minister of The United Kingdom,” Trump wrote on his social media network. “He failed badly on two very important subjects—IMMIGRATION AND ENERGY (OPEN NORTH SEA OIL!). I wish him well!”
The White House did not provide any intelligence sources or evidence to back up the assertion. Downplaying any diplomatic inside tracking,
Downing Street officials confirmed that the two world leaders have not held any phone conversations over the weekend.
Energy tensions explode amid Middle East crisis
The friction over energy between Washington and London has intensified following the military blockade of the Strait of Hormuz by Iran, which has sent global petroleum and gas prices soaring.
The Trump administration has repeatedly pressured the UK government to lift its strict regulatory bans on deep-sea drilling and open up new oil and gas exploration licenses in the North Sea to help calm global energy markets. However, Starmer has held fast to his administration’s green energy policies and climate targets, refusing to allow new fossil fuel licenses—a stance that has drawn public condemnation from Trump.
The Makerfield catalyst and internal rebellion
While Trump’s public prediction lacked formal confirmation from London, British media reports indicate that Starmer is indeed facing a career-defining crisis that could force him to announce a departure timetable as early as Monday.
The political pressure on the Prime Minister reached a breaking point following a high-stakes parliamentary by-election in Makerfield.
The election was decisively won by Greater Manchester Mayor Andy Burnham, a powerful populist rival within the Labour Party who ran on an explicit platform to “change Labour” and “change the country.”
With Burnham now securing a direct seat in the House of Commons, he is legally positioned to launch a formal leadership challenge against the Prime Minister.
The scale of the internal rebellion against Starmer has widened significantly over the weekend. More than 100 elected Labour lawmakers—representing roughly one-quarter of the party’s entire strength in parliament—alongside several high-profile cabinet ministers, have privately and publicly urged Starmer to step aside to prevent a total collapse in nationwide opinion polls.
If Starmer yields to the pressure and steps down, he will become the sixth British prime minister to exit office in a turbulent ten-year span, plunging the United Kingdom into yet another round of intense political transition.
