Blue Labour, the informal Labour policy group established by Ed Miliband advisor Maurice Glasman, is to be effectively disbanded.

Labour MP Jon Cruddas and Middlesex University academic Jonathan Rutherford have both informed Lord Glasman they no longer wish to be associated with the project following an interview given by the controversial peer in which he expressed a belief that immigration to the UK should be completely halted.

A third influential supporter, Dr Marc Stears, is said by friends to be "deeply distressed" by Glasman's comments, and is also considering his future engagement with Blue Labour.

Asked by the Daily Telegraph's Mary Riddell whether he would support a total ban on immigration, even if just for a temporary period, Lord Glasman replied, "Yes. I would add that we should be more generous and friendly in receiving those [few] who are needed. To be more generous, we have to draw the line."

In response to a further question on whether he supported Welfare Secretary Iain Duncan-Smith's call for British jobs for British workers, he responded, ""Completely. The people who live here are the highest priority. We've got to listen and be with them. They're in the right place -- it's us who are not."

The Telegraph profile is the latest in a series of increasingly eccentric interviews and public appearances given by the Labour Peer, in which he has attacked David Miliband, Tony Blair, Gordon Brown and Neil Kinnock, and claimed his agenda is influenced by Aristotle, Miles Davis, Aldo Moro, Lionel Messi and the Pope.

Last month Labour Justice spokeswoman Helen Goodman circulated a critique of Blue Labour to all members of the Parliamentary Labour Party in which she claimed, "[Glasman] characterises as female all the aspects of New Labour he dislikes, whereas all the characteristics he applauds he draws as male. It looks more like something suitable for the psychotherapists' couch than a political tract."

"If Glasman thinks we will all greet this with an ironic post-feminist smile, he is wrong. How can we in a country where 1,000 women are raped each week? He seems to be harking back to a Janet and John Fifties era".

Lord Glasman had been warned by both Cruddas and Rutherford that his media appearances were alienating potential supporters, and had asked him to lower his profile. Both men told friends they believed they had been give guarantees that he would do so, with Rutherford reportedly describing his latest intervention as "a breach of faith".

One source close to Blue Labour said, "Both Cruddas and Rutherford repeatedly told Maurice to tone it down, but he ignored them. Their view is the Blue Labour brand is now too contaminated to continue with the project in its present form. They still hope it will be possible to salvage some of the ideas and themes, but Maurice's actions have made supporting Blue Labour in its present incarnation untenable."

Lord Glasman has formed part of what has been described as Ed Miliband's "long-term strategy group" which meets regularly with the Labour leader on Sunday afternoons. Other members of the group reportedly include Guardian journalist John Harris, Jonathan Rutherford, Chuka Umunna, IPPR director Nick Pearce and Compass chair Neal Lawson.

However, Glasman's most recent comments have alarmed Miliband and his team. "Ed values a lot of things Maurice has raised, such as his focus on strong communities," said a source, "but there are a lot of elements of Maurice's agenda he doesn't agree with, and it's a myth that he has become Ed's main policy person."
