The Leader of the House William Hague has thrown down the gauntlet to Labour over English devolution.
After a meeting at Chequers between the Prime Minister and backbench MPs, it emerged that the Tories plan to press ahead with what were said to be "robust proposals" to give English MPs control over English laws.
"If other parties make it impossible to deal with these issues in tandem, " Mr Hague warned.
People living in the North of England consider Westminster "extremely remote" and want powers closer to them to improve services, according to a council leader.
Labour leader of Manchester City Council, Sir Richard Leese, told BBC Radio 4's Today programme it was not a case of "one size fits all".
He said: "This is not an issue of who votes on what in Westminster.This is about taking power away from Westminster - not devolution to England or even devolution to Scotland, it's devolution in England, devolution in Scotland.
"I make this argument that the leader of Glasgow would make exactly the same argument about the need for powers to go away from Holyrood to cities in Scotland as well."
If last week was about "country before party" this week it's a very different story.
Cameron may have wrong-footed Labour, but there may also be serious rumblings from his own backbenchers, if he wavers on England's future.
Following the promise of further powers for Scotland, David Cameron is now talking about a new deal for the other home nations.
