Investing.com - British Prime Minister David Cameron is to step down by October after the U.K. voted to leave the European Union.
Prime Minister Cameron made the announcement in a statement outside Downing Street after the final referendum result was announced.
He said he would attempt to "steady the ship" over the coming weeks and months.
Cameron had said he would stay in his job no matter the result of the referendum, but his position became untenable after spending months campaigning for a vote to remain in the EU.
The U.K. voted by a substantial margin to exit the EU, with the Leave side winning 52% of the vote, against 48% to remain.
Scotland, Northern Ireland and London voted overwhelmingly for remain, but Wales and the U.K. outside London strongly backed Brexit.
The referendum turnout was 72%, with more than 30 million people voting.
UKIP leader Nigel Farage said the Leave campaign had won a victory for "real people", and said 23 June should go down as "Independence Day".
