It is always just about possible that if Labour are unpopular in 2029 and Reform implode, the Tory leader could become Prime Minister, even of a minority government.
So given the choice (well it is technically one) between someone whose policies I object to, and someone additionally whose personal conduct (corrupt in my opinion), I will choose the one whose policies are the only objection.
So holding my nose, I'd prefer Kemi Badenoch over Robert Jenrick.
