Ian Bremmer shares his insights on global politics this week, discussing Boris Johnson's tenuous status as UK PM, US Secretary of State Blinken's visit to Ukraine, and the volcano eruption in Tonga:

Will Boris Johnson resign?

It certainly looks that way. He's hanging on by his fingernails. He's losing members of Parliament. He's giving shambolic media interviews. In fact, I think the only people that don't want him to resign at this point is the Labour Party leadership, because they think the longer he holds on, the better it is for the UK opposition. But no, he certainly looks like he's going. The only question is how quickly. Is it within a matter of weeks or is it after local elections in May? But feel pretty confident that the days of Boris Johnson are numbered.
