The candidates for the Dorset North constituency are:
- Conservative - Simon Hoare
- Labour - Pat Osborne
- Liberal Democrat - Thomas Panton
- Green Party - John Tutton
The area is currently held by the Tories and Mr Hoare is the current MP.
He won the seat at the last election with a 56.6% share of the votes.
This year's ballot papers are being counted at Blandford School.
The Oxford East count is well underway at Oxford Town Hall, described by political reporter Bethan Phillips as "the country's classiest election count".
Previously a safe Labour seat, there might have been a bit more uncertainty tonight after the retirement of Andrew Smith, MP since 1987.
But Bethan said the exit poll showing a significant swing to Labour "ripped through the hall" and had some party members "literally jumping for joy".Copyright: BBC

Portsmouth Labour think they've done well, big turnout especially from students.
If that's the case, Conservatives will need UKIP voters to switch to them, to hang on to both seats.
Across our region, we have reporters at the counts across Berkshire, Dorset, Hampshire, the Isle of Wight and Oxfordshire.
We'll be bringing you all the news and reactions from the candidates and declarations.
The BBC's exit poll is predicting the Conservatives to be the largest party - but short of an overall majority.
The exit poll indicates that the Conservatives will be the largest party but will lose 17 seats with a projection of 314 seats.
The poll suggests Labour will get 266 seats - a rise of 34 seats.
It puts the Liberal Democrats at 14 - an increase of six, SNP 34, Plaid three and Greens one, and UKIP will lose their only seat. The other parties will account for 18 seats between them.Copyright: BBC
