Scotland's First Minister Alex Salmond has said that the latest opinion polls showed the race for independence was tightening as he promised that oil and gas policy in the North Sea would be more stable in an independent Scotland.
Mr Salmond said there had been 16 tax changes in the North Sea in 10 years and 14 oil ministers in 17 years.
"One of the things that a Scottish control of oil and gas would offer is a much more stable long-term policy," he said in an interview on BBC radio.
David Cameron is expected to claim that only the UK Government has the financial muscle to boost oil production in the North Sea.
Is it a coincide the Cabinets of both the UK and Scottish governments are meeting in Aberdeenshire on the same day? Of course not.
