Boris Johnson hails David Cameron as ‘brave and principled’

David Cameron has been hailed as a “brave and principled man” by Boris Johnson, after he announced he will quit as prime minister in the wake of his defeat in the referendum on British membership of the European Union.

Mr Johnson said the Brexit vote gave the UK a “glorious opportunity” for a brighter future, and insisted that Britain would remain “a greater European power” outside the future Union of 27 nations.

He was speaking shortly after Mr Cameron visited Buckingham Palace to formally inform the Queen of his decision to hand over the premiership to a new Conservative leader by October.
