The VAST majority of the ones left after Bojo's purge in any case.I think the above statement happens to be true ....... if we're talking about the tories
Assuming they lose the next election (IMO absolutely no chance of getting a majority, so it's an unlikely hung parliament at best for them), it's potentially 2029 before another election. I wouldn't wish death on them, but it's a logical conclusion that a chunk of staunch Tory voters will have shuffled off this mortal coil by then.
Without a pivot away from where the ERG, 30p Lee, Braverman and other assorted loons have them heading, they are going to be out of power for a VERY long time.
