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.
The Prime Minister is "not being straight with the British people" over the cost and complexity of constitutional reform, Ed Balls said. The shadow chancellor accused David Cameron of talking "complete nonsense" over his demands that Scottish MPs be quickly stripped of the right to vote on laws affecting only England.
And he said rushed reforms risked "undermining the Union we have all just fought to save".
Mr Cameron's move to link the change to the cross-party timetable agreed for new powers for Holyrood in the wake of Scotland's rejection of independence in last week's referendum has angered Labour and dominated the start of its annual conference in Manchester.
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.
