People in Scotland are voting in a referendum today on whether to declare independence from the United Kingdom.
Key points on today's referendum:
What is the ballot asking?
The ballot asks: "Should Scotland be an independent country?" Voters will be asked to put a cross in either a Yes or No box.
Polling stations opened at 7am this morning and will close at 10pm this evening.
Nearly 800,000 people registered for postal votes, which must arrive by 10pm London time today.
How will the results be announced?
The result will only be formally announced when all the results from 32 local counts are in.
The chief counting officer will announce each local result as it comes in.
However, either side only needs 50% plus one vote of the total turnout so the result should be clear before every ballot paper has been counted.
Results are likely to start coming through from around 2am tomorrow morning.
However, Scotland's biggest cities of Glasgow, Edinburgh and Aberdeen may not report results until after 5am.
When will the result be known?
A national result will be known "around breakfast time" tomorrow, according to a media release prepared by the counting office.
With the major cities reporting late or last, the result will be uncertain through the night.
The councils with the largest share of the electorate, which could most easily affect the overall result, are Glasgow with 11.35% of the vote, Edinburgh with 8.81% , Fife with 7.05%, North Lanarkshire with 6.27%, South Lanarkshire with 6.09% and Aberdeenshire with 4.82%.
Together, they account for nearly 45% of the electorate.
However, earlier results may provide some indication of how the vote is going, with nationalist-supporting areas such as Moray expected to report early and Orkney, expected to reject independence, also likely to be among the first to declare.
How many people are registered to vote?
A late surge in registrations means that 4,285,323 people are registered to vote.
At 97% of the over-16 population, the electorate is the largest in the nation's history.
The election is open to those 16 years old and over who live in Scotland.
Voters must be a British, qualifying Commonwealth or European Union citizen and must have registered by the 2 September deadline.
