Chuka Umunna withdraws from Labour leadership race

The 36-year-old, who was among the bookies’ favourites in the race to succeed Ed Miliband, said he was not comfortable with the “added level of pressure that comes with being a leadership candidate”.

His withdrawal improves the chances of Normanton, Pontefract and Castleford MP Yvette Cooper and Wakefield MP Mary Creagh who both said they were standing this week.

Mr Umunna said in a statement: “Shortly before the election campaign, I made the decision, in the event that Labour was defeated and a new Leader was to be elected, to stand for the leadership of the party if there was a desire in the party for me to do so.

“I dearly hoped Labour would win the election and it was a decision I would not have to implement.

“I also thought I understood the scrutiny and attention a leadership contest would bring.

“As a member of the shadow cabinet, I am used to a level of attention which is part and parcel of the job. I witnessed the 2010 leadership election process close up and thought I would be comfortable with what it involved.

“However since the night of our defeat last week I have been subject to the added level of pressure that comes with being a leadership candidate.

“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.”

Mr Umunna apologised to those who supported him with his campaign and said he continue his role on the shadow cabinet.

He said: “I know this will come as I surprise to many but I had always wondered whether it was all too soon for me to launch this leadership bid - I fear it was.

“Most importantly, I continued to have very real concerns and worry about this bid’s impact on those close to me.

“I intend to carry on playing my full role as a proud member of our Shadow Cabinet taking on the Tories. I also hope to play a leading role in Labour’s campaign to keep the UK in the EU during the forthcoming referendum which is absolutely crucial.

“Most importantly, I will as ever continue to serve the area I know and love - the Streatham parliamentary constituency.”

Liz Kendall and Andy Burnham, are now competing with Ms Cooper and Ms Creagh to replace Mr Miliband.
