David Cameron is too "chilled out" about devolution for his own good, the chair of the Political and Constitutional Reform Committee has said.

Labour MP Graham Allen decried the Prime Minister's lack of urgency and said it was as if he thought the issue had been resolved because Scotland had an independence referendum.

Mr Allen said there is a threat to the political system from mass public apathy and called for a large transfer of powers to local councils to engage more voters.

He criticised Mr Cameron for focusing on the "relatively small beer" of English votes for English laws in the aftermath of the referendum and for his relaxed appearance before the Commons Liaison Committee to discuss devolution today.

Mr Cameron told the committee that further devolution for Scotland will go ahead as promised, regardless of the progress of the controversial plans for English votes for English laws.

During a backbench debate on devolution, Mr Allen told the Commons: "The Liaison Committee met this morning and we had in front of us the Prime Minister. The subject was devolution.

"And there were times during that discussion this morning when the Prime Minister was too chilled out really for his own good in terms of devolution.

"There was a lack of urgency, it was almost as if the problem had been resolved because a referendum had taken place in Scotland.

"Words like 'We need to settle this down now' or words like 'There's no need to rush at these things'.

"Well, what the Scottish referendum did outside of Scotland - vitally important inside Scotland, of course - but what it did outside Scotland but actually allow us to realise what we could do also with a level of engagement and participation which should excite us all when we see some of the threats to our own broader political system in the union."

He went on: "On the West Lothian question itself, it does seem a little bit strange that the very thing that led a lot of people to be turned off of our politics and a lot of people to be lured by separatism is now replaced in our thinking by something actually relatively small beer.

"It is a standing orders question, it is a Westminster bubble question.

"And I'm sorry that the Prime Minister, after this fantastic adventure in democracy in Scotland, as the result was barely dry, was on the doorstep of No 10 Downing Street talking about EVEL (English votes for English laws) rather than talking about the possibilities of further devolution for the rest of the United Kingdom.

"So let's deal certainly with the West Lothian question but let's see it for the relatively small issue that it is when you look at the relatively broader aspect of devolution."
