New challenge to British PM Keir Starmer's leadership

Is the United Kingdom on the verge of replacing another Prime Minister? The incumbent Sir Keir Starmer faces fresh challenges to his leadership today, beginning with the resignation of his Health Secretary Wes Streeting, who has already called on the Prime Minister to step down after disastrous local election results last week. Meanwhile, the Mayor of Manchester, Andy Burnham, says he's going to stand for election to return to Parliament, and he could challenge Mr Starmer if he wins that by-election.Also in the programme: reflections on the meeting between Presidents Trump and Xi in Beijing; and we look at the dinosaur with the tiny brain, said to be as heavy as nine elephants.(Photo: Prime Minister Keir Starmer and MP Wes Streeting who has just resigned as Health Minister.
