Shadow cabinet minister Chuka Umunna was caught out when questioned about his party's team in Scotland after only being able to identify two of Labour's senior MSPs.

Asked to list members of the shadow cabinet at Holyrood he could only name Scottish leader Johann Lamont and Kezia Dugdale - although he did not know her education portfolio.

Mr Umunna said he could not identify any more "off the top of my head", but added: "I'm not a Scottish MP and I'm not a member of the Scottish shadow cabinet."

During the interview with Andrew Neil on BBC2's Newsnight, Mr Umunna insisted Labour's approach to constitutional change would be "bottom up", involving civic society, rather than the Westminster-focused process offered by Prime Minister David Cameron.

On the prospect of English votes for English laws, Mr Umunna said: "The Scottish have just voted to remain part of our union and now this seeks to exclude Scottish MPs.

"What we want to come up with is a constitutional settlement that is inclusive and actually gives people power."

Mr Umunna, who represents Streatham, added: "I'm a London MP, there are certain issues which are devolved down to the Mayor and the Greater London Authority. Are you going to therefore suggest that I should be excluded from things?"

Setting out Labour's plan for a constitutional convention, Mr Umunna insisted it would not take as long as the similar process established in Scotland in 1989 which took six years.

"We are not talking about six years in this instance," he said, adding that "more details will be brought forward shortly".

He said: "What we are aiming to do is a bottom-up process. It's no good the great and the good coming onto programmes like this in Westminster dictating to people what we are going to do with our constitution. That has been the problem, that is why so many people have been switched off."

"In terms of the constitutional convention, there will be initial dialogue, we will come forward with details on that in the coming weeks and then, in the autumn of 2015 we will set up this constitutional convention which will be bottom-up, involving civic society."

The Prime Minister has announced that devolution of further powers to Scotland will run alongside his reforms for England and the rest of the UK.

Mr Umunna insisted that the timetable promised to Scotland would not be delayed, but Mr Cameron's plan would not "cut it" with the people of Britain.

"I don't think there is any proposal on the table which will delay the timetable which has been set out for the proposed devolution in respect of Scotland," he said.

"In terms of what happens in England, well we haven't actually seen any proposals from the Prime Minister at all on that. All we have seen is a proposal to set up a Cabinet committee, again very Westminster-focused, headed by a former leader of the Conservative Party William Hague.

"I just don't think that will cut it with the British people."
