The fever of Conservative Europhobia runs so hot, it has already burnt through a series of supposedly sacred Tory principles. Tories still boast that they are the Conservative and Unionist party, but when they are told that Brexit imperils the union – by jeopardising both Northern Ireland’s peace and its place in the United Kingdom – they shrug. Tories like to say they cherish the supremacy of parliament; indeed the reassertion of Westminster sovereignty was one of the driving purposes of Brexit. Yet now they whip their MPs to pass an EU withdrawal bill that will strip the Commons of its powers, allowing ministers to channel Henry VIII as they rewrite the law of the land unhindered and unscrutinised. They insist that free trade remains a cardinal principle of modern Conservatism as they rush to leave what is, broadly defined, the largest, freest free-trade area in human history.
