More than 130 businesses have signed a letter arguing that the business case for Scottish independence has not been made.

The signatories for the letter, which has been published in The Scotsman, come from a variety of businesses including Caithness Potatoes and The Baxters Food Group, plus others from the banking, mining, engineering, food, whisky, and technology sectors.

Scotland goes to the polls in the referendum on 18 September, with voters being asked to answer whether they want Scotland to become an independent country.

The letter was organised by Keith Cochrane, the chief executive of the engineering firm, Weir Group. According to BBC News, its backers claim that no political organisations have been involved in putting together the list.

The letter states: 'Our economic ties inside the United Kingdom are very close, and support more than a million Scottish jobs. As job creators we have looked carefully at the arguments made by both sides of the debate. Our conclusion is that the business case for independence has not been made.'

The signatories account for about 50,000 jobs in Scotland, according to BBC News, which also noted that supporters of an independent Scotland point to their own supporters from business and economics.
