Keir Starmer has vowed he will quit as Labour leader if he is fined by Durham Police over Beergate.
In a high-stakes attempt to regain control, Mr Starmer tied his future to the results of the police investigation - in a stark contrast with the law-breaking Prime Minister.
Mr Starmer said he was "absolutely clear no rules were broken" but added: "If the police decide to issue me with a fixed penalty notice, I would of course do the right thing and step down."
