Excellent summation, thank you. I think most of the feverish speculation over the weekend would have benefited from such a clear statement.
Certainly, I’ll stop talking about a Portuguese Coup.
The UK convention, that the sitting PM has the first opportunity to form a government, seems to get round putting any sort of discretion on to the head of state, and presumably the rule here that the leader of the single largest party gets the first opportunity seems to do the same.
And as with the UK, the real question is who can command a majority in Parliament.
