The UK Independence Party has never been a professional outfit. Yet even by its standards it has made a farcical start to the year. Two weeks ago it emerged that Jo Marney, the girlfriend of Henry Bolton, the party’s leader, had sent a slew of racist text messages, including about the soon-to-be-royal Meghan Markle. Mr Bolton quit the relationship but not his job. The party’s national executive committee has unanimously voted that it has no confidence in him, and more than a dozen colleagues have resigned in protest. Next up is an emergency meeting of members in February. Mr Bolton has been in charge only since September, but if he hangs on until mid-April he will be the longest-serving of UKIP’s past five leaders. The party’s days look numbered. Yet as it sinks into chaos, the government continues to press on with Brexit—the national earthquake that UKIP brought about. Its members may well reckon they are having the last laugh.
