Theresa May resigns as UK Prime Minister on Friday. What happens after?

First it's a question of the Conservative Party. The members of parliament deciding on the two candidates that they think are worthy to go for a ballot with 160,000 members of the Conservative Party. The two candidates will be there, ready by the end of June and the balloting should be ready by the end of July. So by then we would know who will be the next UK prime minister. Boris Johnson might be in the lead today. Expect surprises along the road. The choice is certainly going to be important much to come from that.

Will the Czech prime minister also resign?

Well the background is, of course, the massive demonstrations in Prague the other day. Really massive with accusations of corruption. I don't know. I was there. No one really seems to know. I think the Minister of Justice might be in more of the immediate danger zone but certainly an issue worth to follow.
