Scots started going to the polls to vote on secession from 7am this morning - but they will have to wait 24 hours to hear the final result of the vote.
How will it work? We all know how vote-counting goes at a general election - but an independence vote like this is unprecedented in the UK. With the turn-out rate expected to be above 90 per cent, just counting the vote is set to be a mammoth task.
Voting is broken down into 32 local government areas, which will declare individually from 2am, with the last one - Aberdeen - voicing its decision at 6am. The result of the election should be clear by 7am.
