The majority of Labour members say they do not believe Keir Starmer can turn around the party’s fortunes, while 45% say the prime minister should step down.

The mayor of Greater Manchester, Andy Burnham, was the first preference for 42% of members, who were asked to rank their preferred successor.

Several Labour MPs – especially those who are close to Burnham – have told the Guardian that they would like to see a timetable for Starmer to stand down in an orderly and dignified way, including allowing the mayor time to seek a parliamentary seat.
