The campaign is in full swing. On June 23, Britain will decide by referendum whether to leave the European Union (EU). Most of the political establishment, including the leaders of all the main parliamentary parties, are arguing for a “remain” vote. But the country is unimpressed, and opinion polls remain evenly balanced.

In Britain, the vote is a very big deal. We have had only two national referendums before, and one of those, back in 1975, was also on leaving the EU. Those campaigning for withdrawal, including me, see it as an opportunity to restore our independence, our democracy and our economic freedom. We want to reorient Britain away from the enervated and declining eurozone toward the rest of the world. Since 2007, the GDP of China and India have both roughly doubled; but that of the eurozone, incredibly, remains the same size.
