Boris Johnson will remain Prime Minister and win an 86-seat majority, according to exit polls conducted by Ipsos MORI.

The Conservatives are set for a 368-seat victory, according to an exit poll for the BBC, ITV and Sky News. This would be the best result for the Conservatives since Margaret Thatcher’s victory in 1987.

The results would see a 50-seat gain for the Conservatives compared to 2017. Labour would lose 71 seats, with a total of 191 MPs – the biggest Labour loss since 1935.

The SNP would see 55 seats – a gain of 20 – while the Lib Dems would get 13 seats and Plaid Cymru three. The Green Party would get one seat, and the Brexit Party would get none, according to the poll.

The official counts will be rolling in all night, with final results due in by lunchtime on Friday.

How accurate is the exit poll?

Exit polls are considered more accurate than opinion polls. In 2017, Ipsos MORI forecast a slight majority for the Tories, but it fell short of predicting a hung parliament.

How does the exit poll work?

The Ipsos MORI exit poll is a projection based on 144 polling stations across England, Scotland and Wales. Pollsters conducted 22,790 interviews, asking voters to indicate how they voted on a replica ballot. The constituencies are chosen demographically, with a balance between rural and urban areas.
