I’m pretty ambivalent on the issue, especially as everyone is very keen on by-elections when it’s someone they don’t like but keeps quiet when someone joins the party they support.
But when I didn’t vote for Jenrick, the ballot paper made it very clear he was representing the Conservative and Unionist party, so there clearly is an argument that he was elected on a basis that is no longer the case and, if he’s going to be representing a different party going forward, he should stand again.
It’s not the same as the party leader conversation, because my ballot paper didn’t mention Keir Starmer at all.
