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 says his party will lay out proposals for further devolution across the UK in the "coming days".
He said the party already had plans for devolution in England but added "we want to go further".
He appeared to dismiss calls for an English parliament, saying: "I don't think that has actually been proposed but we will look at any proposals the Prime Minister comes forward with."
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.
