As the right hon. Gentleman knows very well, the greatest damage that could be done to the Scottish economy would be the SNP’s reckless plan to break up the Union with the UK. Sixty per cent. of Scotland’s exports are with the rest of the UK. They would be throwing away not just the biggest block grant in history that Scotland has received this year but, of course, all the benefits of membership of the most successful political partnership in history, from shipbuilding in Govan to the Glasgow climate change summit next year, which will be a glory of our whole United Kingdom and which is coming to Scotland precisely because Scotland is part of the United Kingdom. They would throw all that away with their crackpot plan for borders at Berwick and creating a new Scottish currency or joining the euro; and, worse still, going into the European Union and handing back control of Scotland’s fisheries—Scotland’s spectacular marine wealth. Just at the moment that they have been won back by this country, they would hand back control of those fisheries to Brussels. That is their policy; I look forward to contesting it at the barricades.
