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.
Labour leader Ed Miliband has said that the vote on the Scottish referendum was a "wake-up" call for the establishment on how the country and the economy are run.
Mr Miliband, speaking on the Andrew Marr show, said: "Unless the establishment recognises this wake-up call about how our country is run, how our economy is run, we are not going to address the discontent in England, Wales, Scotland and the whole of the United Kingdom."
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.
