Britain Votes to Leave European Union

British voters have elected to leave the European Union, sending the pound down more than 10 percent to its lowest level since 1985.

Turnout across the United Kingdom was 72 percent, with Scotland solidly in the "remain" camp while southern England and Wales propelled the "leave" faction.

With about 30 million votes in, the "Brexit" campaign was triumphant by 52 percent to 48 percent.

The fallout was expected to reverberate in future referendums. Sinn Féin leader Martin McGuinness said in March that a Brexit win should be followed by an Ireland reunification vote. Fifty-six percent of Northern Ireland voters elected to remain part of the EU.

Scotland, which voted by 62 percent to remain in the EU and voted against independence from the UK in 2014, is expected to revisit the possibility of a split.

"Scotland must keep open every option for protecting ourselves from this threat. The Scottish Parliament and government must be represented in the negotiations about what comes next," said member of parliament Patrick Harvie, co-convener of the Scottish Greens. "A cross-party plan of action should be sought, so we can defend our rights as EU citizens."

The UK Independence Party, led by Nigel Farage, was doing a victory lap before the race was even called.
