Boris Johnson's days as British Prime Minister are limited, and if he continues to cling on, he'll be forced out.
That's the view of former Attorney General and British Conservative MP Dominic Grieves.
Mr Johnson's currently fighting for his job - after losing both his Chancellor and Health Secretary yesterday.
They quit after he apologised for appointing Chris Pincher as his deputy chief whip - saying he'd 'forgotten' about complaints over his behaviour.
Dominic Grieves says another confidence motion will likely be held, despite the current rules stating they could have to wait 12 months:
''I think that in reality there will be another confidence motion, they'll change the rules.
Or if there isn't another confidence motion the pressure that's going to build on him will be so great that his position will become untenable.
It's very difficult, it's a very unusual situation, If he was any ordinary Prime Minister he would already be gone.
His character and temperament mean will cling on and have to be forced out.''
