However, Ed Miliband, the Labour leader, has indicated that he will not support the “English votes for English laws” reform. The plan would harm Labour’s political power base: Mr Miliband has 40 out of the 59 Scottish constituency seats in Parliament. In other developments:



• Plans were being considered to recall Parliament on Thursday or Friday – interrupting the annual party conference season – to allow MPs to debate the Scottish referendum and devolution reforms.



• A close ally of Mr Miliband warned that Labour’s opposition to Mr Cameron’s plan will trigger “an English backlash” from traditional Labour supporters in the North which could cost the party next year’s election. A senior source said: “It’s dreadful. The Conservatives could now win on the back of this. We don’t seem to have an answer.”



• A Telegraph/Opinium Research poll of 1,000 adults found support across the UK for Mr Cameron’s plan. Six in 10 adults thought it was right to ban Scottish MPs from voting on English laws.



• Gordon Brown pledged that the resolution signed by Mr Cameron, Mr Miliband and Nick Clegg, the Liberal Democrat Leader, will go ahead irrespective of opposition in the House of Commons.



• Alex Salmond, the Scottish First Minister, said the No camp had already started to “tear up the commitments”.



• Conservative backbench MPs drew up plans to force a vote in the Commons on the new Scottish devolution deal. Some predicted a rebellion that would “dwarf” the Tory uprisings over Europe if ministers did not scrap the Barnett formula, which gives Scotland proportionately more state funding than England.



• The Prime Minister invited more than 20 senior Tories – including some of his most outspoken critics – to lunch at Chequers, his country retreat, to head off the revolt. Downing Street said he “wants the Conservatives to be seen to be standing up for England”.
