Armed Forces minister Al Carns and a couple of junior frontbenchers followed the Defence Secretary John Healey in resigning from government last night.
Healey's accusation was a stinging one - that Keir Starmer is failing to commit to keeping the nation safe from attack. That, after Starmer pledged only a few months ago to put "petty politics" to one side and be bold on British defence.
He now faces a testing week like no other. His Defence Investment Plan, long delayed. is due to be launched on Monday. Can that go ahead? If the PM gets through that, he faces the prospect of Andy Burnham returning to the Commons on Friday - who could instantly make a move for the top job.
How damaging have the resignations of the past 24 hours been for Starmer's already dwindling prospects of staying in the job? And how on earth does the PM navigate the next week?
