The countdown to the General Election 2019 is firmly on.
Polling stations open at 7am on Thursday and close at 10pm.
As polling stations close, the exit poll will be released.
What’s an exit poll?
The poll will estimate the total number of Commons seats expected to be won by the Conservatives, Labour, the Liberal Democrats, the Green Party, the Brexit Party, SNP, Plaid Cymru, and others.
Opinion research specialists Ipsos Mori will interview tens of thousands of people as they leave 144 polling stations across the country.
As they leave, they will be asked to mark on a mock ballot paper how they had just voted.
Polling experts contracted to each channel will help to produce the results.
Who does the exit poll?
BBC News, ITV News and Sky News will combine forces to release the same exit poll once voting ends on election night.
It will be the fourth exit poll to be produced by the three broadcasters as they did in 2010, 2015 and 2017.
Is it right?
Exit polls have produced the right results.
In 2017 there was widespread shock that it showed a hung Parliament – however, when the results came in that was just what happened.
But, two years earlier, another hung parliament was considered the likely outcome by those behind the 2015 exit poll but David Cameron produced the first outright Tory majority in more than 20 years.
