What time to expect 2019 UK Election results
Polls have opened in what has been described as the United Kingdom's most important general election in a generation.
Prime Minister Boris Johnson is facing off with Labour's Jeremy Corbyn in a contest fought over the UK's Brexit stalemate and the country's national services.
All 650 seats in the House of Commons are up for grabs in an election two years ahead of schedule and the first to be held in December in 96 years.
All major opinion polls prior to election day suggest Johnson is heading for a narrow win, however the possibility of a hung parliament is not off the table.
What time will the UK Election results become clear?
9am Friday AEDT (10pm Thursday local time): Polling booths will close.
In what will be the first major indication of how the election will unfold, an exit poll commissioned by multiple British broadcasters including the BBC, ITV and Sky will be released.
That poll, based on surveys taken of voters from 144 constituencies across the UK after they have left voting booths, should provide an idea of how each of the major parties have performed in this year's election.
The accuracy of exit polls has always been a contentious issue, however the last survey conducted – during the 2017 general election – correctly predicted the Conservatives would be the largest party represented in the parliament.
10am AEDT (11pm local time): Within an hour, the first results are expected.
In what has become a lighthearted race, there are two constituencies that compete to see which will count votes quickly enough to be the first to call a result.
Those seats are Houghton and Sunderland South, and Newcastle Central, both in England's north and both currently held by Labour.
11am AEDT (midnight local time): Results are expected to be slow as millions of votes are counted.
It is expected, however, that by midnight results could become clear in major seats targeted by Johnson's Conservatives, such as Darlington, Wigan, and Workington, which has been held by Labour since the 1970s.
If Labour does lose any of these seats, it will be an indication as to whether Corbyn might have any chance to win the election.
Midday to 1pm AEDT (1am-2am local time): About 200 results are expected to be declared over two hours.
Some of the crucial results to watch include in the Conservative seats of Dartford, Loughbrough, Nuneaton and Chingford, and Woodford Green.
A result is also expected from the northern English seat of Hartlepool, currently held by Labour, but contested by Nigel Farage's Brexit Party candidate Richard Tice.
2pm AEDT (3am local time): In what could be a telling moment for Corbyn's chances, results should start flowing in from the 'Red Wall' of Labour-held seats across the centre of England.
The Conservatives have targeted the region heavily in the hope of breaking a chain of historically-strong Labour constituencies.
The major seats of contention that could mark a huge loss for Corbyn include Bolsover (held by Labour for 50 years), Ashfield, Canterbury, and Easher and Walton.
If any of these seats do turn blue with a Conservative win, it will be a major indication Johnson may be heading towards a parliamentary majority.
3.30pm AEDT (4.30am local time): Another key moment as a result is expected for the Prime Minister's own seat of Uxbridge and South Ruislip.
In a break with tradition, Johnson chose not to vote for himself in his own marginal seat, instead registering in Westminster. It is a bold image given a heavy tactical campaign to oust him from his own constituency.
Johnson managed to hold his seat in 2017 by a slim margin of just 5034 votes. The last time a Conservatives leader was unseated in their own electorate was in 1906.
5pm AEDT (6am-7am local time): A result should be clear, with almost all of the 650 constituencies decided by sunrise.
One of the last seats to be decided is expected to be Richmond Park, in the Greater London area.
It's considered an ultra-marginal seat after it was won by the Conservatives' Zac Goldsmith in 2017 by just 45 votes.
His closest opponents this year are Labour's Sandra Keen and the Liberal Democrats' Sarah Olney.
