Relations between Donald Trump and Keir Starmer have been further strained by the Iran bombing. Keir Starmer has hit back at Donald Trump after the US president criticised the UK for not initially helping America bomb Iran. Trump said he was “very disappointed” in the prime minister for refusing the US permission to use the Diego Garcia military base to launch air strikes against the regime in Tehran. He told the Daily Telegraph it “sounds like” Starmer was “worried about the legality” of using the base. But in a Commons statement on the conflict, the PM said: “We believe that the best way forward for the region and the world is a negotiated settlement in which Iran agrees to give up any aspirations to possess a nuclear weapon and ceases its destabilising activity across the region. “That has been the longstanding position of successive British governments. “President Trump has expressed his disagreement with our decision not to get involved in the initial strikes. “But it is my duty to judge what is in Britain’s national interest. That is what I’ve done, and I stand by it.” This is a breaking news story and will be updated. Follow HuffPost UK on Twitter , Facebook and Instagram . Related...
