Britain’s Observer newspaper said Prime Minister Keir Starmer was expected to resign Monday and set out a timetable for his departure, though a government source said Starmer remained focused on getting ?on with the job of governing.

The threat to Starmer’s position, which has been building for months, increased sharply ?on ?Friday, when his rival Andy Burnham won a seat in parliament that would allow ?him to launch a formal leadership challenge.

The Observer report said Starmer was discussing the matter with his wife at his Chequers country residence before making a final decision, but that senior Labour figures expected a clear statement on ?his future as early as Monday.
