In the build-up to the tenth anniversary of the EU referendum, we’ve heard lots of claims about Bregret. There are some Remain nostalgists who are convinced that, after a decade of listening to their wise counsel about how much better we’d be if we’d stayed in the glorious EU, those misled numpties who voted the wrong way must surely have changed their minds and be ready to slink back to Brussels. Recently, the Observer commissioned polling to prove the point. It’s true that rejoining attracted the largest single share, at 33 per cent. But the options for staying out of the EU, taken together, commanded a clear majority: 55 per cent. Mysteriously, the paper decided not to publish. Darn it, why does the public keep giving the wrong answer? Intrepid researchers from a new initiative, Britain Unbound (I am on its advisory board), wondered if this was a one-off and went back through Opinium’s published data. They found a poll from 20 May posing a simpler question: was the idea of rejoining the EU acceptable or unacceptable? A majority of 54 per cent called it unacceptable. That poll, too, was commissioned by the Observer and, again, the findings were filed in a drawer labelled ‘inconvenient truths’.
