GLASGOW, SCOTLAND - SEPTEMBER 18:  Felipe Perez walks out of polling station at Notre Dame primary school with a Saltire flag, on September 18, 2014 in Glasgow, Scotland. After many months of campaigning the people of Scotland today head to the polls to decide the fate of their country.  The referendum is too close to call but a 'Yes' vote would see the break-up of the United Kingdom and Scotland would stand as an independent country for the first time since the formation of the Union.
