One of Labour's biggest rising stars, the shadow business secretary Chuka Umunna, has declined to rule out a future Labour leadership bid.
Mr Umunna, a employment laywer who became an MP in 2010, professed his loyalty to the leader Ed Miliband but also did not deny that he has ambitions for the top job.
The MP for Streatham, 33, said he was "uncomfortable" with questions about his future plans but raised the prospect of a vacancy in "two or three years'" time.
He was speaking at an event hosted by Channel 4 News at the Labour party conference, which is being held this week in Manchester.
Asked if he hoped to become leader, he said: "I feel so uncomfortable with these questions. I just think there is something very unhealthy about pre-supposing you alone would be the best person to make very big decisions involving life and death decisions for some people in this country at some point in the future.
"It would be incredibly arrogant for me, or anyone else to say, in two or three years I would be the best person to lead this country. I feel deeply uncomfortable about that."

Mr Umunna was spotted by Mr Miliband in his 20s and the party leader helped him become an MP then made him is Parliamentary Private Secretary.
He was then promoted to the shadow cabinet in October 2011.
Questioned about the speed of his rise, he said: "I'm just impatient. I cannot tell you how hungry I am for us to win the next general election. I'm fed up with being in the shadows."
In a wide-ranging interview, the MP dismissed claims he has a large entourage and suggested he would like an even bigger team.
"Frankly we don't have enough people. Capacity issues are major. The people who work for me, as far as I'm concerned, are underpaid," he said.
"They work 24/7 for the Labour party and because they are deemed to be an expense they are not paid what they deserve for serving my community or serving us nationally as a party. I think it is outrageous."
He added: "I'm ashamed of what we pay the people who work for us."
Mr Umunna also spoke movingly of the harrowing impact of his father's death in a mysterious car crash in Nigeria when he was just 13.
Bennett Umunna was reportedly murdered for his anti-corruption stance when he was standing for state governor in the nation.
"There was a lot of speculation in Nigeria at the time around his death. He was a national political figure standing on an anti-corruption ticket and refused to bribe anybody," Mr Umunna said.
"We don't really talk about it because it is not going to bring him back." He added: "I think he would be bowled over that his son does what I do."
The MP also told delegates he sang the theme tune for the comedy Mr Bean TV series when he was a chorister at Southwark Cathedral.
