That decision could come back to haunt them. The final trade relationship between the U.K. and the EU has yet to be determined, but it’s likely that barriers to trade will be erected.Some of the regions that voted Leave also have the highest dependency on trade with the EU.This could be particularly damaging to the northeast and Yorkshire and Humber, who rely on the EU for 62 percent and 55 percent of their region’s exports, respectively. Wales, which exports a total of 67 percent of its goods to the EU, also voted Leave.By contrast, some of the regions that voted most overwhelmingly to remain, like Scotland and the London area, have more diversified export portfolios, meaning their post-Brexit trading prospects could be less damaged by any new barriers.The POLITICO Global Policy Lab is a collaborative journalism project seeking solutions to challenges faced by modern economies in an age of political disruption and technological transformation.

If the U.K.’s decision to leave the EU was driven — at least in part — by anger over rising inequality, Brexit risks making things worse.Britain is one of the most unequal of all developed countries, according to the NGO LIS Cross-National Data Center. Thirty-one percent of the country’s income goes to 10 percent of its people, and wealth is even more starkly disparate: The richest 10 percent holds 45 percent, while the poorest half owns less than 9 percent.Wealth inequality correlates with the vote to leave. Some of the poorest regions in the country had the largest majorities in favor of Brexit.
