Farage and his mates in the new ukip - I think it’s called ‘reform’ wouldn’t under any circumstances rub along with the tories.
The nicotine stained liar is spitting nails about what he sees as a softening on brexit - ‘betrayal’ he called it- by sunak’s government and sees it as his duty to disrupt and challenge them at the next GE.
Since the tories hoover up all the right/centre right votes in Britain, a serious rival which bases its policies on a blind devotion to the failed, but still popular in certain sections of the vote, concept of brexit, it could split the right wing votes enough to let labour in.
I imagine members of the ERG and the likes in the Tory party wouldn’t mind since it is obvious that they see their philosophy as being a lot closer to farage and may even see joining ‘reform’ as the way forward for themselves and brexit since they clearly hold no devotion to the tories an would happily bring them down.
It‘s pretty much single issue politics on the hard right.
Either way, it’s going to split the right-wing vote.
