David Cameron on Wednesday pleaded with Scottish voters not to use the independence referendum to give the 'effing Tories' a kicking.In an extraordinary intervention, the Prime Minister appeared close to tears during a speech in Edinburgh in which he acknowledged the unpopularity of the Conservatives in Scotland but warned the result of next week's vote will stand for 100 years, Daily Mail reported.He cancelled his appearance at PMQs to travel to Scotland, leading Alex Salmond to claim Team Westminster is 'panicking', adding: 'The movement in Scotland is decisively towards Yes.'It comes amid fresh warnings that Scotland faces being plunged into a 'deep recession' as pensions firm Standard Life revealed plans to move jobs to England if independence is backed by voters and oil giant BP warned said the North Sea oil industry is 'best served' by Scotland remaining part of the UK.Mr Cameron cleared his diary to travel to Scotland, after polls showed the Yes and No camps are neck-and neck with barely a week until the historic referendum on Thursday September 18.The PM said: 'Because it is an election people think it's like a general election. If you are fed up with the effing Tories, you can give them a kick and then maybe we'll think again. This is totally different.'This is not a decision about the next five years, but the next century.'Mr Cameron went on: 'This vote is not about whether Scotland is a nation or not, Scotland is a nation, it's a strong, proud nation with an extraordinary history and incredibly talented people.'But it is a nation that has chosen over the last 300 years to be part of a family of nations. A family of nations that enables this great country to punch way above its weight in the world.'This vote is not about Scotland versus Britain it's about two competing visions for Scotland.'I hope you choose the vision of Scotland that is about Scottish pride, Scottish patriotism, Scottish nationhood, but is also about being part of the family of nations we have created.'Mr Cameron cancelled his appearance at Prime Minister's Questions today to visit Edinburgh, while Mr Miliband is in Glasgow and Mr Clegg will campaign in Selkirk.
