WHITEHALL, LONDON, UNITED KINGDOM - 2016/07/02: A demonstrator on Whitehall shouts towards Downing Street during the pro-EU "March for Europe", tens of thousands strong, nine days after the deeply divisive British vote to leave the European Union. Britains referendum on EU membership saw a narrow 52 percent victory overall for those voting "Leave", with Leavers winning by various margins across much of the country (though in highly-cosmopolitan London, and across Scotland, voters preferred unambiguously to "Remain"). The result prompted the immediate resignation of British Prime Minister David Cameronwho had campaigned for the UKs continued membership of the blocas well as a tumbling in value of the British pound and a reported spike in incidents of anti-immigrant hate crime.
