Supporters of Greater Manchester Mayor Andy Burnham expect senior members of Keir Starmer’s cabinet to tell the UK prime minister to agree a handover of power in the coming days, in an attempt to make it impossible for him to continue in post.

One of Keir Starmer’s leadership rivals, Wes Streeting, says he is ready to force an immediate contest if the UK Prime Minister does not step down after a special parliamentary election on Thursday.
