David Cameron is expected to make a major statement on the future of the UK this morning.

Mr Cameron is expected to respond to Scotland's decision in a live televised address to the nation from 10 Downing Street following the declaration of the final results at around 7am.

His statement will come as the Tory backlash against the promise of extra powers for Holyrood from the three main UK party leaders intensified, with Claire Perry becoming the first Coalition Minister to join the complaints.

Mr Cameron is expected to set out not only proposals to devolve more powers to the Scottish Parliament, but also significant changes to the constitutional settlement for other parts of the country.

Conservative Chief Whip Michael Gove, a close ally of the Prime Minister, indicated that this could involve reforms to ensure only English MPs can vote on English issues at Westminster.

Asked if he thought Scotland had voted to remain in the UK, Mr Gove told Sky News: "It does look as though - and I'm keeping every limb crossed - the United Kingdom will be safe."

Mr Gove said Mr Cameron was "anxious to ensure that, after this referendum campaign, we can bring the United Kingdom together".

After joining Ed Miliband and Nick Clegg to promise further devolution to Holyrood if Scots voted No, the Prime Minister is facing pressure from MPs south of the border for a similar extension of powers to the English regions, or even the creation of an English Parliament.

Mr Gove said Mr Cameron's statement would recognise "that Scotland needs enhanced devolution... (and that) it's also important to recognise that the rest of the United Kingdom needs to have its position enhanced as well, in Northern Ireland, in Wales and, of course, in England".

He added: "We need to look again at the arrangements which look after the people who live in the majority of the United Kingdom and I think the Prime Minister in particular will be spelling out some ways forward which will allow Westminster to change how it operates in order to ensure that the interests of English voters are effectively protected - indeed enhanced."

In her local paper, Claire Perry, a Wiltshire MP warned Scotland should not be offered "promises of financial party bags" and decried the "whole raft of goodies on offer for Scotland that will be paid for by us south of the border to appease the Yes voters".

Ms Perry, believing there will be a No vote, said she expected Westminster to be recalled next week to debate the new deal of more powers and retention of the Barnett funding formula being offered by David Cameron, Nick Clegg and Ed Miliband.

"If there is a proposal to allow devolution of local taxation as well as maintaining the current level of funding as a dollop from the UK parliament, then that can hardly be equitable for those of us in the Devizes constituency and all other area areas in the non-Scottish Union," she added.

Fellow Wiltshire Tory, James Gray, a former Shadow Scottish Secretary, also echoed the disquiet of the so-called three party leaders' "vow" to Scotland.

He said: "Talk about feeding an addiction. The more you give them, the more they want and we would be back with calls for independence within a decade or sooner."

Mr Gray, Glasgow-born and whose father was a Moderator of the General Assembly of the Church of Scotland, said he would reluctantly back the "foolish" new deal for Holyrood if the imbalance between Scotland and England were addressed.

He claimed: for too long Scottish MPs had voted on English matters; the number of Scottish MPs must be "culled appropriately"; there should be greater powers for the "long-suffering people of England" and the Barnett Formula, which gave each Scot £1500 a year more than their English counterpart, "must be swept away with no delay".

Mr Gray added: "For too long the rights of 55m English have been subordinated to the shouting of 4.5m Scots. That must end."

Conservative backbencher Philip Davies, who represents Shipley in Yorkshire, branded the proposed new Unionist deal for Scotland as misguided, saying: "It was done in a panic when the polls narrowed. It was completely ill-thought through."

He made clear he was not prepared to give a "blank cheque to Scotland that my constituents will have to pay for" and promised not to vote for the new deal "under any circumstances".

Ex-party whip Michael Fabricant, the Tory MP for Lichfield, made clear, even if the result were a No, serious questions had to be asked about the "complacent mishandling of the vote by No 10 and the incompetence by Miliband".

Tory former Cabinet minister Liam Fox said change is "unavoidable" to address the ability of Scottish MPs to vote on devolved issues in Westminster, while Labour's John Denham called for devolution within England.

Meanwhile, regional newspapers in northern England united to launch a campaign for greater powers to tackle an "uneven playing field" in the UK.

Dr Fox said the cross-party vow to give more powers to Holyrood meant the "English question and the West Lothian question" has to be addressed as there is an "imbalance in our constitutional relationship".

He told BBC2's Newsnight: "There are a number of ways that we can address that but I think now it will have to be addressed. Politicians have ducked the question for too long."

The Scot added: "I'm not in favour of a separate English parliament, because I think with parish councils, town councils, district councils, county councils, Westminster, the last thing we require is another level of government.

"But I do think effectively what we must ensure is that Scottish MPs, who cannot vote on issues like health and education in Scotland, should not be entitled to vote on health and education in constituencies like mine in North Somerset.

"It is profoundly undemocratic and unfair, that needs to be dealt with."

Dr Fox, who was born in East Kilbride, also raised questions about the funding arrangements being promised for Scotland and the implications for change in England.

"I have thought for a long time we need to look at deprivation indices across the country when we are allocating funding and I think we have a strong incentive to do that."

Setting out his plans, Mr Denham told the programme: "At first you've got to have a constitutional convention in England. Secondly, we are going to have change in Westminster, it's clear that the more powers that go to the Scottish Parliament, the less you can have Scottish MPs voting on the same issues for England, that's got to change in one way or another.

"Thirdly, though, England is much too centralised. So this isn't just about reducing the influence of Scottish MPs in Westminster, it's about getting English decisions out of Westminster."

Shadow international development secretary Jim Murphy also said the independence referendum in Scotland could bring about changes south of the border too.

He told the BBC that there would be "much more power and more decisions made in Scotland".

He added: "The House of Commons is going to have to get used to that and the rest of England is going to have to get used to that.

"There's a real sense of disconnect between the village of Westminster and real peoples' lives across the whole of the United Kingdom so I think there will be an English awakening, of a sense of how can they do politics differently in England.

"I'm not going to dictate what that should be, but I think England will change as a consequence of Scotland changing."

In a display of unity, northern titles including The Journal, Chronicle, Northern Echo, Gazette, Yorkshire Post and Manchester Evening News issued a joint demand for devolved power.

All the papers carry the same front page message calling for the North to be given "far more control over its own affairs".

Referring to the "vow" to Scottish voters from the Prime Minister, Deputy Prime Minister Nick Clegg and Labour's Ed Miliband, which was carried on the front page of the Daily Record in the run-up to polling day, the newspapers urged the three leaders to make a similar promise to the North.

The message said: "The North of England is already competing on an uneven playing field, squeezed by an economically-strong London to the south and Scotland to the north.

"We know that we have what it takes to succeed if we're given the tools to do the job, creating jobs in the North - and boosting the economy of UK plc."

Journal editor Brian Aitken said: "The unprecedented coming together of the great Northern newspaper brands should send a clear message to our politicians that it is vital they make sure the North does not suffer from having an economic powerhouse to the south and a far more competitive Scotland to the north."

Peter Barron, editor of the Northern Echo, said: "The guarantee of additional powers for Scotland - irrespective of the referendum result - presents particular challenges for the North of England. The Northern Echo is happy to be joining forces with other major regional newspapers to call on party leaders to ensure the North of England is not overshadowed or neglected."

Jeremy Clifford, editor of The Yorkshire Post, said: "The debate over the referendum in Scotland has opened up a much wider call for increased powers for the regions.

"We are joining with newspaper titles across the North to ensure this vitally important part of England does not lose out in the aftermath of the Scotland decision."

The Conservative MP for the Humberside constituency of Brigg and Goole, Andrew Percy, said in a series of tweets: "A No vote victory does not mean no change. That includes England. Time for an English Parliament.

"England must have an English parliament in the event of a No vote. Time for a federal UK.

"We can have an English Parliament at Westminster as well as the British seat. England must be heard as much as Scotland."

The chairman of the House of Commons Political and Constitutional Reform Committee, Graham Allen, said: "If we really believe in devolution, the leaders' 'vow' should apply to all nations in the union, not just Scotland.

"Devolution needs independent local government, income tax assignment and a federal parliament, not an English one."
