The most often-heard argument against a second vote on British membership of the European Union is also the least plausible. By this account, revisiting the issue would be "divisive". Old wounds would never close. Deal or no deal with Brussels, the sooner the barricades are thrown up across the Channel, the sooner a spirit of national unity can be restored.
This relies on the outlandish assumption that the 48 per cent of Brits who voted in 2016 to remain part of the EU are now content to hum the English nationalists' tunes.
