CLAIMS made by the No camp made in the run-up to the referendum are already falling apart, the SNP has said.

The main Westminster parties pledged to work together to devolve further powers to Holyrood in a bid to secure votes against independence, but within days rows broke out over what shape political reforms should take.

Concern over the creeping privatisation of the NHS in England was a major focus during the Labour party conference last week. A central argument for the Yes campaign was that this could pose risks to the finances of Scotland's NHS and the SNP has accused Labour of hypocrisy for insisting the health service north of the Border was safe with Westminster before the referendum.

Meanwhile, in the days following the referendum, new research has been published suggesting that decades could be added to the lifespan of North Sea oil reserves and warnings have been issued over looming austerity cuts for the UK.

SNP MSP Annabelle Ewing said: "During the referendum campaign, the No parties made a number of claims which are already falling apart.

"The No camp won't be allowed to forget their vow to transfer substantial new powers to Scotland."

Here we examine some of the key issues raised before the referendum - and what has emerged since polling day.

OIL

BEFORE THE REFERENDUM: The Yes camp pledged to set up an oil fund in an independent Scotland, similar to that operated by Norway, to invest the revenue from up to 24 billion barrels of oil still to be extracted from the North Sea.

But eight days before the referendum, oil tycoon Sir Ian Wood said he believed there were around 15-16 billion barrels of recoverable oil left, and no more than 35 years of oil and gas production remain without any new significant discoveries. His comments came despite publishing a report just six months earlier, in which he referred to a "24 billion boe [barrels of oil equivalent] prize potentially still to come". Oil economist Professor Alex Kemp and industry body Oil & Gas UK backed the figure of up to 24 billion barrels of oil and gas still to recover.

NOW: A major technology boost which could add decades to the lifespan of oil reserves in the North Sea was announced last Wednesday. Researchers at Edinburgh's Heriot-Watt University said they had been working on developing methods to cleanly and cheaply extract valuable remaining oil from existing fields. Currently, at least half of the original oil still remains in the North Sea reservoirs, but there are huge challenges in extracting it which make it too expensive to pursue. But the Heriot-Watt team said they believe they can identify which fields would benefit from a relatively inexpensive technique known as low-salinity water injection.

Professor Mehran Sohrabi, director of the university's centre for enhanced oil recovery, said it was a "massive leap forward, especially in an off-shore setting".

When asked about the timing of the report, a spokeswoman for Heriot-Watt University said: "Heriot-Watt has been conducting research to enhance the recoverable percentage of this oil for over 30 years. Far from the information having been suppressed, Energy Minister Fergus Ewing himself recently visited Heriot-Watt's Institute of Petroleum Engineering, including touring Professor Sohrabi's laboratory to discuss his most recent research on enhanced oil recovery."

THE NHS

BEFORE THE REFERENDUM: The Yes campaign argued that while NHS policy is devolved to Scotland, independence would be the only way to ensure financial protection of the health service north of the Border. Fears were raised that NHS reforms in England resulting in increasing privatisation could mean reduced UK Government spending on health south of the Border, and therefore reduced funding for Scotland through the Barnett Formula. But the No campaign accused the Yes campaign of scaremongering and lies over the issue.

The No campaign also seized on documents leaked three days before the referendum that were said to suggest the NHS in Scotland is facing a funding gap of up to £450 million and major changes would be needed for health boards to break even.

NOW: The SNP have accused Labour of hypocrisy over the NHS for placing the idea of battle for the "soul of the NHS" at the heart of the party's conference last week, despite Labour arguing throughout the referendum campaign that health service funding for Scotland was safe in Westminster's hands. Shadow health secretary Andy Burnham said: "Make no mistake - this coming election is a battle for the soul of the NHS. The fight of our lives." Ed Miliband also focused on the NHS during his final conference speech before the election. He said: "The NHS is sliding backwards under this government. They are privatising and fragmenting it. Just think what it would look like after five more years."

SNP MSP Annabelle Ewing said: "Labour's hypocrisy on the NHS has been completely exposed - saying the health service would be safe with a No vote before the referendum, and then just days later saying it is in fact being privatised by David Cameron, which poses risks to Scotland's NHS."

In response Neil Findlay, Scottish Labour's health spokesman, said: "The only people who can privatise our NHS are the Scottish Government."

Meanwhile, Health Secretary Alex Neil last week insisted the funding gap of up to £450m was a "myth".

BARNETT FORMULA

BEFORE THE REFERENDUM: The scrutiny over the Barnett Formula intensified during the independence debate. Under the system, Scotland receives more spending per head than the UK average: some say this reflects the difficulty in providing services to remote communities, but critics claim it means Scotland is being "subsidised" by the UK.

The vow issued by David Cameron, Ed Miliband and Nick Clegg before polling day pledged the formula would remain and stated: "Because of the continuation of the Barnett allocation for resources, and the powers of the Scottish Parliament to raise revenue, we can state categorically that the final say on how much is spent on the NHS will be a matter for the Scottish Parliament."

NOW: The motion laid before Parliament by the three party leaders on the Monday following the referendum did not make any mention of the continuation of the Barnett Formula, a move which was led to warnings of an "unforgiveable breach of faith" by finance secretary John Swinney.

Senior Conservatives were reportedly furious at the pledge for the Barnett Formula to continue. Labour Leader Ed Miliband defended the Barnett Formula last week on the opening day of his party's conference, but his shadow Welsh secretary Owen Smith said it could be adjusted to benefit Wales.

Last week Alex Salmond questioned the Liberal Democrats' support for the Barnett Formula, saying Scottish leader Willie Rennie would have to clarify what exactly the party was proposing. In 2012, the LibDems' Home Rule Commission, led by Sir Menzies Campbell, said any future devolution must recognise "that the Barnett Formula was only ever intended to be a temporary measure". But a pre-manifesto document published by the LibDems in September stated: "In order to ensure reliable funding at this time, we will retain the Barnett Formula as the basis for future spending allocations for Scotland."
