MPs should abandon the crumbling Houses of Parliament in favour of a less confrontational modern chamber, a senior Labour MP has suggested.

Former Labour leadership candidate Chuka Umunna said the debate over how to conduct urgent repairs costing up to £7 billion was an ideal moment to move forward.

He suggested the historic Palace of Westminster could be turned into a tourist attraction.

"It's a beautiful building and it often feels like you are in a museum. So why don't we turn it into a museum?" he asked in an interview with the Evening Standard.

"How in 2015 is it that we are carrying on with a Commons that cannot even seat all its members? How can we continue with a chamber that nurtures the ridiculous tribalism that switches so many people off?" - suggesting a semi-circular arrangement like that used in many other countries instead.

"I think that would change the nature of debate. Sketchwriters would hate it."

It was revealed recently that the taxpayer faces a bill of up to £7.1 billion to stop the Palace of Westminster falling down unless MPs and peers agree to move out while the work takes place.

A study by independent consultants has highlighted the appalling condition of Parliament - with potentially deadly fire risks, collapsing roofs, crumbling walls, leaking pipes and large quantities of asbestos.

If politicians refuse to leave the building, patching it up to basic standards will take around 32 years and could cost between £4.9 billion and £7.1 billion.

Some MPs have suggested the work could be used as a chance to move Parliament out of London for good, and bring with it civil servants in a massive decentralisation of power.

Birmingham Library has been suggested by some as a potential venue, but it is unlikely MPs would want to move out of the UK capital because of the inconvenience and the fact government ministers and civil servants work in Whitehall.

Even if they relocate to another venue and allow renovation teams free run of the historic site, it will still need six years and an estimated £3.5 billion capital outlay.
