Prime Minister David Cameron is to step down by October after the UK voted to leave the European Union.

Mr Cameron made the announcement in a statement outside Downing Street after the final result was announced.

He said he would attempt to "steady the ship" over the coming weeks and months.

He had urged the country to vote Remain, warning of economic and security consequences of an exit, but Leave won by 52% to 48%.

England and Wales voting strongly for Brexit, while London, Scotland and Northern Ireland backed staying in.

UKIP leader Nigel Farage hailed it as the UK's "independence day" but the Remain camp called it a "catastrophe".

The pound fell to its lowest level against the dollar since 1985 as the markets reacted to the results.

The referendum turnout was 71.8% - with more than 30 million people voting - the highest turnout at a UK-wide vote since 1992.
Wales and the majority of England outside London voted in large numbers for Brexit.

Labour's Shadow chancellor John McDonnell said the Bank of England may have to intervene to shore up the pound, which lost 3% within moments of the first result showing a strong result for Leave in Sunderland and fell as much as 6.5% against the euro.

'Independence day'

UKIP leader Nigel Farage - who has campaigned for the past 20 years for Britain to leave the EU - told cheering supporters "this will be a victory for ordinary people, for decent people".

Mr Farage - who predicted a Remain win at the start of the night after polls suggested that would happen - said it would "go down in history as our independence day".

He called on Prime Minister David Cameron, who called the referendum but campaigned passionately for a Remain vote, to quit "immediately".
