Shortly after the exit poll is published at 10pm, check back here to find what it forecasts for where you live.
The exit poll was carried out on Thursday by Ipsos UK for Sky News, the BBC and ITV News.
The forecasts won’t be updated when vote counts are revealed, so keep across our live updating results page to see the real results for every constituency, and then come back here to compare them with what the exit poll said.
What is an exit poll and how does it work?
It’s different from an opinion survey. People are selected at random as they leave polling stations having just voted, and asked to complete a ballot identical to the official one.
So it asks them what they have just done, rather than what they will do in the future which normal opinion polls do.
It is intended to measure changes in vote shares from the previous election in specially chosen constituencies. This year’s exit poll included 133 polling stations, so only a small fraction of the 632 constituencies in Great Britain (Northern Ireland is not included in the exit poll).
The majority of constituencies are selected because they reflect the battle between the two main parties – Labour and the Conservatives. A smaller number represent battlegrounds between the Liberal Democrats and each of the two main parties.
The increased representation of the SNP in Westminster has meant additional polling stations have been added in Scotland in recent years to track SNP/Conservative and SNP/Labour battles.
The political and statistical experts that form the exit poll team, including Sky News election analysts Professors Michael Thrasher and Will Jennings, look to create models that explain changes in how people have voted from one election to the next, based on demographic indicators and social characteristics such as age, housing and education, for example.
In 2019, how people voted in the EU Referendum in 2016 emerged as a leading indicator that correlated with the vote swing from Labour to the Conservatives, in areas where the exit poll was carried out.
The exit poll team were able to use that to predict that the Conservative vote share was likely to have increased more in other high Leave-voting areas across the country, even in places where they didn’t ask anyone how they voted.
