An hour by hour guide of the UK General Election night

Click on the individual times to view the commentary


The U.K.’s general election is actually 650 separate votes in 650 individual districts. Most seats won’t change hands, and the outcome of only about 100 will determine the final tally for Theresa May’s Conservatives and Jeremy Corbyn’s Labour Party.

If the result is close in any given district, a recount could delay the announcement. The key to interpreting these results as they come in is the concept of swing, the shift in votes from one party to another compared with the previous election in 2015, which is used to estimate how many seats might change hands. At the moment, the polls are very mixed. The most favorable for May suggests a swing of close to 3 percentage points to the Tories, which might increase their majority to 80 seats or more. The least favorable, with a swing of more than 2 points to Labour, sees the Conservatives losing perhaps 15 seats and their parliamentary majority.

  • Voting ends

    10 p.m

    Voting ends across the U.K.

    X 10 p.m - Voting ends across the U.K.
    • Voting ends across the U.K. and broadcasters release their exit poll.

    • Last time, it gave the Tories 316 seats, short of a majority, to Labour’s 239.

    • The Tories actually ended up with 331 and Labour 232.

    • At some point during the night, once enough results are in, the number crunchers for TV stations including Strathclyde University’s John Curtice will produce projections of the final result.

  • 11 p.m.

    Sunderland count finishes first

    X 11 p.m. - Sunderland count finishes first
    Sunderland runs a slick operation to ensure its count finishes first, and is scheduled to announce results before midnight.

    • These should be safe Labour seats - no Tory has won here since 1959. The interest will be in changes to vote shares as a pointer to later results.

    • Labour had more than half of the vote in all three Sunderland seats in 2015, while the U.K. Independence Party took about 20 percent.

    • With UKIP collapsing in the polls, have its votes gone to Corbyn’s party or May’s? It’s worth noting that YouGov polling during the campaign showed the biggest regional swing to the Tories was in the northeast.

  • Battersea and Putney

    1 a.m.

    Battersea and Putney results

    X 1 a.m. - Battersea and Putney results
    • The results from strongly pro-EU but Conservative-held Battersea and Putney are scheduled to give the first indication of how the election played out in London, where the Tories have found it difficult to take votes from Labour.

    • We should now see a trickle of results coming in but, unless there’s a major shock, none of these early seats is likely to change hands.

  • Labour held seats

    1:30 a.m.

    Three results in Labour-held seats

    X 1:30 a.m. - Three results in Labour-held seats
    • This where things get interesting… we’re due to get three results in Labour-held seats about now that will show whether the Tories are making gains.

    • In Wrexham, in north Wales, the Conservatives need a swing of 2.8 percentage points from Labour. A gain would suggest they’re on course to increase their majority to more than 50 seats.

    • Back in the northeast, the Tories need a 3.8-point swing in Darlington - a win there might indicate they’re on course for a majority of about 75 seats.

    • Also due up is Tooting, in south London, which is potentially winnable for the Tories on a swing of 2.7 points from 2015. It was a district where an estimated 75 percent voted to stay in the EU, so could also indicate how Brexit has affected voting.

  • 2 a.m.

    50 results in by now

    X 2 a.m. - 50 results in by now
    • The pace starts to pick up; we should have about 50 results by now.

    • If the Tories are gaining seats, there will be further evidence of the scope of their success, a win in Bury South, in Greater Manchester, where they need a 5.2-point swing, might point to a majority of more than 100.

    • But there are targets now for Labour too, including just next door in Bury North, where fewer than 200 voters need to switch from the Tories for the opposition party to regain the seat.

    • Labour needs a 2-point swing in Peterborough; a win here would indicate there might be a hung Parliament, where no party has a majority.

    • The first results will also be coming in from Scotland, where the Tories have been gaining support from First Minister Nicola Sturgeon’s Scottish National Party. Angus, to the north of Dundee, is the Tories’ 11th most-winnable seat north of the border, so may be out of reach.

    • The Liberal Democrats are also seeking to win back Fife North East, which includes the university town of St. Andrews, from the SNP.

  • Result from Corbyns Islington London due

    2:30 a.m.

    Result from Corbyn’s Islington London due

    X 2:30 a.m. - Result from Corbyn’s Islington London due
    Hartlepool is an ambitious target for the Conservatives in the northeast; it’s only the 65th most-winnable for the party on a swing of 7.4 points.

    • Labour targets from the Tories include the very marginal district of Vale of Clwyd, in north Wales, and Warwickshire North, in the Midlands, where the opposition party needs a 3.1-point swing.

    • The result in Corbyn’s Islington North constituency in London is due about now; his victory speech (it’s a very safe Labour seat) will no doubt be live on TV and may hint at information he’s received from party activists at counts across the country.

  • 3 a.m.

    Getting toward peak results time now

    X 3 a.m. - Getting toward peak results time now
    • The Tories will be looking for gains in winnable Labour districts across the country: both seats in Newport, in South Wales, a city where they last had a lawmaker elected in 1983, and two in Labour-leaning Coventry, in the West Midlands.

    Stockton North, in the northeast, may also be a target on a 10.6-point swing after the Conservatives unexpectedly won the election for Tees Valley regional mayor last month. Meanwhile, if Labour can take Erewash, in the East Midlands, and Northampton North, the opposition party is likely to be on course for more than 260 seats, cutting the Tories back to some 300.

    Ealing Central & Acton is theoretically the most winnable London seat for the Tories, but it voted heavily to remain in the EU so may stay Labour.

    Dagenham & Rainham recorded the highest Leave vote in London, so may be in play for the Conservatives, despite the 8.5-point swing needed.

    • There are three big Tory targets in Scotland about now, the latest Scottish poll suggested the Conservatives will gain six seats from the SNP, and Perth & Perthshire North, Moray and Renfrewshire East are within that range. Not only did Moray score the highest Leave vote in Scotland, it’s the seat of the SNP’s deputy leader, Angus Robertson.

    • Liberal Democrat Jo Swinson needs only a 2-point swing to win back Dunbartonshire East from the SNP, but if the Lib Dems are having a bad night, their leader Tim Farron may be vulnerable to a Tory surge in Westmorland & Lonsdale, in northwest England.

  • Third votes in

    3:30 a.m.

    More than a third of results will be in by now

    X 3:30 a.m. - More than a third of results will be in by now
    • If the Conservatives are on a roll, they could take Sedgefield, in the northeast, which needs an 8.8-point swing from Labour; it’s former Prime Minister Tony Blair’s old constituency.

    • In London, Ilford North, Enfield North and Westminster North are all vulnerable to smallish swings to the Tories.

  • 4 a.m.

    This will be the busiest time…

    X 4 a.m. - This will be the busiest time…
    • … Although the shape of the new Parliament should already be fairly clear, unless it’s really close. If it is, there are some key results to look for.

    • Labour targets include Gower, in South Wales; their most winnable target overall, and Croydon Central and Hendon, their most winnable in London, as well as both districts in Plymouth, where May campaigned this week.

    • The Tories will have their sights on Labour seats in the Midlands, including Walsall North and Newcastle-Under-Lyme.

    • It’s make-or-break hour for the pro-EU Liberal Democrats. Former Business Secretary Vince Cable is seeking to win back Twickenham, in southwest London, from the Tories; next door in Kingston & Surbiton, former Energy Secretary Ed Davey is attempting a similar feat.

    • In Richmond Park, Sarah Olney is bidding to retain the district she won in a by-election last year, while in inner London, Simon Hughes is aiming to wrest his old Bermondsey constituency back off Labour.

  • 4:30 a.m.

    Two-thirds of the results should be in

    X 4:30 a.m. - Two-thirds of the results should be in
    May will speak in her Maidenhead constituency, west of London, after the result there is announced.

    • Key marginals include Wolverhampton South West, in the West Midlands, where the Tories need just a 1-point swing.

    • Former Liberal Democrat leader Nick Clegg may be under pressure from Labour in Sheffield Hallam.

  • 5 a.m.

    If it’s still going down to the wire…

    X 5 a.m. - If it’s still going down to the wire…
    • We’re due results from some of the 10 most-winnable Labour-held Tory targets: City of Chester and Wirral West, in northwest England, Halifax, in Yorkshire, where May launched the Tory manifesto, and Brentford & Isleworth, in west London.

    • Bristol West is the Greens’ number one target for a second Commons seat. UKIP leader Paul Nuttall is running in Boston & Skegness in eastern England.

    • The Tories will have their sights on Labour seats in the Midlands, including Walsall North and Newcastle-Under-Lyme.

  • 600 votes

    6 a.m.

    More than 600 results should be in by now.

    X 6 a.m. - More than 600 results should be in by now.
    Derby North and Brighton Kemptown are must-win Tory-held targets for Labour.

    Berwickshire, Roxburgh & Selkirk is the most winnable Scottish district for the Tories.

    • If the result is clear, expect May or Corbyn to make a victory speech at some point over the next few hours.

  • 7 a.m.

    One late result of interest will be Thanet South, Kent

    X 7 a.m. - One late result of interest will be Thanet South, Kent
    • Tory incumbent Craig Mackinlay was charged during the campaign over alleged overspending in the run-up to his victory over UKIP’s Nigel Farage in the 2015 election. He denies the charges.

    • Apart from that, it’s almost all over. There are only six more results set to trickle in over the course of the morning, with the final three not due until 12 noon.

    • By that time, if we know who the prime minister is, the focus will switch to the first announcements of who’s in the new cabinet.

    If it’s a hung Parliament, the discussion will be about possible coalitions or deals to prop up a minority Tory or Labour administration.
