The US president shocked the world this morning what declaring that Israel and Iran "don't know what the f*** they're doing" as both sides were accused of violating the ceasefire he announced.
Our political editor Beth Rigby put to Sir Keir Starmer that it's all rather humiliating for Donald Trump, particularly given his close personal relationship with Israeli PM Benjamin Netanyahu.
But Starmer dodged that question, saying a ceasefire was in place "in the early hours of today", which is "a good thing for the region and more widely".
"We need to maintain that ceasefire and I think it's very important at this NATO summit that we all work together to make sure that we do, because that ceasefire creates the space for what needs to happen next, which is the negotiations to ensure that Iran does not have the capability to develop nuclear weapons," the PM said.
He added: "I want to see that ceasefire maintained. We will work with others, including, of course, the US, to ensure that that's the position."
