Sajid Javid warned Tory cabinet ministers "not doing something is an active decision" as he pulled apart Boris Johnson's leadership in the Commons.
Refusing to "risk losing my integrity", Mr Javid said "enough is enough" adding, "there's only so many times you can turn that machine on and off before you realise something is fundamentally wrong".
The former Health Secretary wished his cabinet colleagues "well", adding "they have their own reasons", drawing laughter from many in the chamber.
