On a similar note, is it a coincidence that the Communist Party refused to stand any candidates for the first time in 2017 and instead pledged to back Labour as long as Corbyn was leader? You 'suspect' that if UKIP or the Brexit Party took that approach with the Tories, then a reasonable accusation would be that the Tories had veered pretty far to the right. Indeed, they're quite rightly accused of lurching to the right as it is, and yet UKIP/Brexit Party still want them to go further, yet the Communists, who you regard as far left, feel happy enough that Corbyn's Labour represent their views that they don't need to stand any candidates.
