Polls open: Scotland's historic vote for independence

Should Scotland be an independent country? Voters face a straightforward question yes and no, as they head to the polls to cast their ballot in the country’s landmark referendum.

A vote for independence would mean Scotland, with its population of about 5.3 million, separates from the rest of the United Kingdom -- England, Wales and Northern Ireland -- ending the 307-year old union.

With 4,285,323 people -- 97 per cent of the electorate -- registered to vote, it is expected to be the busiest day in Scottish electoral history. We bring you the mood from Scotland, around 15 hours away from making history (or not).

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.
