Boris Johnson has claimed that the UK will not be "any less united" after the Brexit vote.

The most high-profile campaigner to leave the European Union also hailed David Cameron as a "brave and principled man".

But Mr Johnson, expected to be a frontrunner in the race to become Prime Minister, did not mention the ongoing turmoil on the markets.

Both he and his fellow leave campaigner Michael Gove made only short speeches and left without taking questions.

Mr Johnson said that the vote had given the UK a "glorious opportunity" for a brighter future.

Britain would remain "a greater European power" outside the EU, he said.

As Mr Johnson was speaking First Minister Nicola Sturgeon said that another independence referendum was on the table amid the fallout from the result.

The markets opened this morning with carnage in the City of London.

More than £100 billion was wiped off the value of the UK's top companies while the pound crashed 8 per cent against the US dollar.

The markets regained some of the lost value after Bank of England governor Mark Carney pledged to intervene to shore up the markets.

Mr Carney announced £250bn of emergency funding for the economy.
