Eighteen months, one government and two Brexit secretaries ago, David Davis promised that a post-Brexit Britain wouldn’t gut agricultural standards or workers’ rights: we were not entering ‘an Anglo-Saxon race to the bottom, a Britain plunged into a Mad Max-style world borrowed from dystopian fiction’. Last Sunday, details were leaked from Operation Yellowhammer, outlining the Civil Service’s ‘base scenario’ for a No Deal Brexit: port and border chaos is expected, along with food and fuel shortages and disruption to medical supplies; there is a ‘plan to evacuate the queen’ in case of civil unrest. Priti Patel, the home secretary, has promised the immediate end of free movement on the first day of a No Deal Brexit, threatening the status of EU nationals resident in Britain and British nationals abroad, but tickling the bellies of the Tory base. Lobbying from the backbenches, Iain Duncan Smith praised thinktank proposals to raise the state pension age to 75 as ‘removing barriers’ to work.
