Why Britain voted to leave (and what Boris Johnson had to do with it)

Some Leavers claim the referendum result was not primarily about immigration, but anxiety about Britain’s perceived loss of sovereignty to the EU. In their new book, Harold D. Clarke, Matthew Goodwin (left) and Paul Whiteley draw on data about more than 150,000 voters to analyse the factors and concerns that led people to vote Leave. The mix of calculations, emotions and cues were complex, but immigration – and the personal appeal of Nigel Farage and Boris Johnson to different groups of voters – were key.
