Having helped the UK leave the EU it's now clear that UKIP is descending into farce, faction fighting, incoherence, and potential irrelevance as its newly elected leader, Diane James, resigned last night after just eighteen days in office. This would be of no consequence but for three reasons.
The first is that this is yet another indication of the collapse of parts of British politics.
The second is that the fate of UKIP looks to be a foretaste of the Brexit troubles to come for the UK as a whole.
And third, put the two together and then wonder on the risk to the Conservatives when they too realise that the issue that kept many of their members in the party ceases to be a totemic dream and becomes an electoral curse.
