Rees-Mogg said on Newsnight that if there is a change of leader he thinks there needs to be an election. No doubt we will hear this a lot over the next day or two, since it is designed to scare the red-wallers into supporting Johnson given their slim majority.

If this is true, either they call an election immediately Johnson goes, and try to fight the next election before they have chosen a leader. Or, alternatively, they choose their new leader who then completely voluntarily throws away their 80-odd seat majority.

Sorry, I don't buy it.
