David Cameron and Alex Salmond have clashed over the future of Scotland's oil and gas industry as they held rival Cabinet meetings within a few miles of each other. The Prime Minister warned that leaving the UK would harm the key sector.
The Deputy Prime Minister has said that the UK should be "really proud" of the fact it is a "world leader" in carbon capture and storage.
Nick Clegg said: "The innovation of the UK's energy industry is something we should be really proud of and the fact that we are a world leader in carbon capture and storage is a great example of our country's ingenuity.
"Today's multi-million pound deal with Shell will help to safeguard thousands of jobs and power half a million homes with clean electricity.
"It shows we can build a stronger economy and do it fairly by protecting our environment for future generations."
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.
