Britons woke in their millions to find the Daily Mail’s promised Ukipocalypse was, if anything, an understatement. Bulgarians have been found hiding in bread bins, behind radiators, inside teapots; Romanians are clogging up bath plugs, nibbling at chocolate bars left on kitchen tables, reading “how to claim benefits” guides loudly in bathrooms.

In 1904, the Tories passed the Aliens Bill to make political capital out of fears about Irish and Jewish immigrants. The aim is always the same: let the elites off the hook, and blame foreigners for all the ills of society instead. Operation Deflect Blame, if you like.

Housing shortages caused by a failure to let councils build; falling wages caused by weak unions, globalisation and a minimum wage declining in real terms; a lack of secure jobs caused by de-industrialisation and austerity: all can conveniently be blamed on The Foreigner.

Then again, truth matters little to politicians determined to deflect blame from themselves and their wealthy backers.
