The head of the Local Government Association, which represents councils in England and Wales, has said "the devolution genie is out of the bottle" following the Scottish referendum.
David Sparks said any new powers that Scotland receives "must be given to local areas in England and Wales", adding: "The appetite for devolution does not stop at the border and the rest of the UK will not be content to settle for the status quo."
The LGA called for an urgent meeting of a Constitutional Convention and called on the Government to set out a timetable for devolution across England, with a pledge for immediate new powers to areas which are ready for them.
The Scottish referendum campaign has shown that public trust in the old ways of central control has been shattered beyond repair. That is why establishing an English Parliament, with MPs still calling the shots, would not represent true devolution.
It is locally elected councils - driving their local economies through devolved taxation and greater control over council tax and business rates - which can satisfy the desire of people in England to have greater say in the places they live and work.
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.
