General election 2017 results night: When will we know who's won?
Here's a full guide to UK general election night on the BBC - including the key results to watch out for as the night unfolds.
What to expect when
Results have started coming in at quite a pace, but there are many more still to come. Most counts will be completed by 06:00 BST.
Some won't be in until lunchtime on Friday, with Berwick-upon-Tweed, Blyth Valley and Wansbeck usually last to declare.
However, the overall outcome of the election should become clear much earlier than that.

Results to watch out for
Here is a full list of estimated declaration times from the Press Association
All timings are approximate
3am Results are coming in thick and fast - at the rate of about five per minute. Lib Dem leader Tim Farron's result in Westmorland and Lonsdale, where he is facing a strong Tory challenge, could be interesting.
4am One of politics' big hitters - Alex Salmond, in Gordon - is expected to be re-elected around now. Results in key Lib Dem targets Cheltenham and Bath are also expected. The Conservatives are targeting three seats in Scotland - the first to declare is likely to be Dumfries and Galloway around now. If they take this seat from the SNP, Theresa May could be looking at a big majority overall. Aberdeenshire West and Kincardine and top target Berwickshire, Roxburgh and Selkirk are set to declare a little later.
4.30am Theresa May faces little threat in Maidenhead, but we could find out what she makes of the national results when she speaks at her count.
5am UKIP leader Paul Nuttall will find out whether he has unseated his Conservative opponent, who was a Remainer, in Boston and Skegness.
