The petition alone won't trigger ambitious or self serving Labour MP's to oust Starmer but it's additional pressure on top of the backlash that has already made itself known. As things stand it's pretty clear that the next election will send the party into a degree of political exile that will make the Liberal party's 100 years in the wilderness look like a day trip to Brighton.
On a related subject as the petition came up during the interview I see that Starmer isn't afraid to go on TV to answer the tough questions...
Cat Deeley and Andy Peters, dear God give me strength. Peters' toughest TV gig to date was sidekick to Gordon the bleedin' gopher.
