Johnson was the best person to lead the Tories in the election. He's since proven himself not to be the best person to be PM.
Is it just my personal opinion? Well let's see.
He was running increasingly bad numbers in polling, with the majority of people wanting him out by the end.
In a vote of confidence, he narrowly won but the majority of his own backbenchers wanted him out. He had enough ministers to get him over the line, but within weeks 50+ of them had resigned - even ones that he had appointed hours earlier!
So yeah, I'm pretty ok with my personal opinion on this one.
