Despite rumours that ReformUK might be willing to enter some sort of electoral pact with the Tories ahead of the next election, Nigel Farage rejected this idea, suggesting that only a 'reverse tax-over' of the Tories is of any interest to him.
Normally I wouldn't comment on Fararge's fantasy politics, but in this case it perhaps confirms what many suspect; that a badly weakened Tory party may be prey to a stronger populist right challenger.
Time & events will tell.
