New rules which restrict the voting rights of Scottish MPs should be urgently and comprehensively rewritten just a year after they were introduced, according to a report by a cross-party group of MPs.

Even English MPs are shunning parts of the controversial 'English votes for English laws' system, the House of Commons Procedure Committee found.

Few if any are speaking in new 'English-only' debates designed to give them a bigger voice in parliament.

The committee said that it was "deeply dissatisfied" with the rules governing Evel, which were "opaque and defy interpretation by" MPs, and did not command support across the chamber.

Hailed by supporters as a way to make the Commons fairer, Evel has also introduced an imbalance, MPs said.

Under the new rules English MPs can veto reforms that would change public spending levels in England, but Scottish MPs cannot do the same for Scotland.

The SNP described the report as “damning”.

The UK Government said it would look at the findings.

David Cameron faced accusations of betrayal after he announced plans to introduce Evel less than an hour after Scotland voted to remain inside the United Kingdom in 2014.

Critics attacked the then Prime Minister saying that the policy should have been announced before the independence referendum.

But the Conservative Government forged ahead, arguing that the previous system had been unfair because it allowed Scottish MPs to vote on issues that did not directly affect their constituents.

The row centres on the 'West Lothian Question', which asks, how, under devolution, a Scottish MP could vote on health issues in Blackburn, Lancashire but not Blackburn, West Lothian.

The report warns that Evel does “not command the respect and support across all parties that they should if the system is to be sustainable through the political stresses it must expect to face in the future.”

It adds: “This is not a sound basis for a major long-term change to the legislative process in this House.”

The committee also found that MPs from south of the Border showed a “lack of appetite” to take part in English-only debates.

The system was "scarcely being used", according to the report.

One Conservative backbencher Jacob Rees-Mogg told the committee that Parliament was left looking "faintly ridiculous" by procedures which mean that "we suspend for a minute, we come back, we pretend to have a committee, which then disappears and then we vote".

The SNP said that that the report was “damning”.

SNP MP Patrick Grady, who is a member of the Procedure Committee, said the findings showed the "fundamental flaws" in the Evel procedures.

"The SNP has consistently argued that this system of Evel effectively excludes MPs from Scotland having a say on major policy changes which can affect the Scottish Government’s block grant.

"The operation of procedures themselves has been a farce, with very few MPs in the Chamber understanding what’s going on, making the House of Commons business even more impenetrable to the public. It’s laughable that the MP who has spoken most often in the ‘Legislative Grand Committee’ which is supposed to give English MPs a voice is Pete Wishart, the SNP MP for Perth and North Perthshire."

He called on the Prime Minister Theresa May to dump Evel.

Charles Walker, the chairman of the Procedure committee, said that he hoped that ministers would use the report as an opportunity "to greatly simplify the procedures around Evel.

"The current procedural complexities around English votes for English laws do no credit to the House," he added.

A UK Government spokesman said ministers were committed to a stronger Union and a fair settlement for the whole of the UK.

He added that they believed that the current arrangements "strike the right balance in providing a clear voice to English MPs while ensuring every MP is still able to vote and debate on all pieces of legislation" but added that ministers would consider the report as part of an ongoing 'technical' review into Evel.
