Streatham MP Chuka Umunna has quit the Labour party leadership contest.

In a statement, the shadow business secretary blamed the "added level of pressure that comes with being a leadership candidate" and said: "I have not found it to be a comfortable experience.

"One can imagine what running for leader can be like, understand its demands and the attention but nothing compares to actually doing it and the impact on the rest of one's life.

"Consequently after further reflection I am withdrawing my candidacy."

Sources close to Mr Umunna insisted that his withdrawal was not due to any negative story which he expects to appear in the media.

It is understood that he was uncomfortable with the increased level of scrutiny which had been directed at him and members of his family since he declared his intention to stand for the leadership.
