GLASGOW, SCOTLAND - SEPTEMBER 04:  Political viewpoints decorate the exterior of premises- one reads 'Vote No' in favour of the Union, the other is a 'Yes' sign for a 'Yes Scotland' pro-independence office, showing opposing sides of the argument for the forthcoming Scottish independence referendum, on September 4, 2014 in Glasgow, Scotland. Scotland will vote on whether or not to leave the United Kingdom in a referendum to be held on September 18th this year.  (Photo by Jeremy Sutton-Hibbert/Getty Images)
