US President Donald Trump on Monday hit out at outgoing British Prime Minister Keir Starmer, saying the Labor Party leader’s policies on energy, immigration and relations with Washington contributed to his downfall.Speaking to reporters during an Oval Office event, Trump struck a friendly tone before launching into sharp criticism of Starmer’s record.“I think he’s a lovely guy,” Trump said, before accusing the British leader of failing to fully exploit the North Sea’s oil reserves and ruining Britain’s energy potential by allowing “windmills everywhere.”Trump said, “Britain buys most of its energy. You know where? Norway. Do you know where they get their oil? The North Sea.” “The UK has a better part of the North Sea – they don’t want to do it for environmental purposes.”Trump, who previously predicted Starmer’s departure in a Truth Social post, said the Labor leader was “my friend in a way” but suggested he had not done enough to support the United States on major geopolitical issues, including NATO and the conflict involving Iran.Trump revealed that one point of contention was Britain’s initial reluctance to approve the use of RAF Akrotiri, a British military base in Cyprus, for US strikes on Iranian targets. The two leaders reportedly clashed over the issue, with Trump expressing frustration over the delay.“They said we couldn’t use the island to land. That was a first,” the MAGA supremo said. He said that Starmer eventually agreed but that it was “a bad move” that “hurt him badly”.As Starmer prepares to step down as Labor leader, Trump said the British prime minister’s “biggest political weaknesses were evident.”“I wish him well,” Trump said. “But he’s got two problems: energy and immigration — and crime. But energy and immigration. “He really hurt himself very, very badly.”Starmer announced on Monday that he would resign as Labor leader while remaining prime minister during a managed transition after months of mounting pressure within his party and a series of disappointing election results that weakened his authority.Attention is now turning to veteran Labor leader Andy Burnham, the former mayor of Greater Manchester, who is widely considered the frontrunner to replace Starmer. If elected, Burnham would become Britain’s seventh Prime Minister in just over a decade.
