Streeting expected to launch leadership bid, allies say, as PM warns any contest would cause 'chaos'

Keir Starmer argues a leadership debate will paralyse the government and cause chaos within the Labour Party. Can this argument shrink the potential support for Streeting or any other potential challengers? But the prime minister also knows that a significant number of his MPs now think he is a loser - and a major factor in the scale of Labour's defeats in elections in England, Scotland and Wales last week. For those wannabe challengers, the challenge is trying to set out a distinctive and attractive alternative Labour agenda, that can appeal to MPs and party members - and convince them they would be more popular than Keir Starmer. There is a big moment coming in the next 24 hours: for Wes Streeting, deciding to go for it or not, and the tone and tenor of any launch that he is planning. For the prime minister, his back is against the wall. And for any others too, with designs on the top job.
