The online reaction to Britain officially voting to leave the EU…

Britain has voted in favour of leaving the EU on an unprecedented night in British politics.

In a move that will have far-reaching effects not just for Ireland but for international relationships and the global economy, the people of the United Kingdom have opted to leave the EU by a margin of 52% to 48%. Votes were frantically counted in polling areas across England, Wales, Scotland and Northern Ireland and the Leave camp won it by a margin of just over one million. https://twitter.com/BBCBreaking/status/746208928384462848 Gibraltar and Newcastle were the first two results in just before midnight for Remain which gave the Stay campaign hope that a victory could be won. Huge swathes of London, South Wales, Northern Ireland and all 32 areas of Scotland voted the same way. But this polling map shows it's Middle England and the North that swung it for the Leave campaign with areas including Boston and Thurrock seeing nearly three-quarters of people voting to exit the EU.

UKIP leader Nigel Farage, who was one of the figureheads of the Leave campaign, was feeling pretty happy with himself this morning... https://twitter.com/Nigel_Farage/status/746201545524416513 https://twitter.com/Nigel_Farage/status/746217696623157249
