Voters are heading to the polls in the Peterborough by-election in a vote called after the previous MP was forced out after being jailed for lying about a speeding offence.
The constituency, which voted Leave by 60.9% in the EU Referendum in 2016, has historically been a closely fought battle between Labour and the Conservatives.
Labour won the seat in 2017 with a wafer-thin majority of 607.
Fifteen candidates are standing in Thursday’s by-election, which was called after Peterborough’s previous MP Fiona Onasanya was forced out after she was jailed for lying about a speeding offence.
Onasanya was elected as a Labour MP and was suspended from the party after she was sentenced.
Both Labour and the Conservatives have campaigned hard ahead of the June 6 by-election, with Labour leader Jeremy Corbyn, former prime minister Gordon Brown and Tory big guns Boris Johnson and Jeremy Hunt all visiting the city in the lead-up.
But Nigel Farage’s Brexit Party, which won 29 seats in the European elections, has also campaigned hard in its first tilt at a Westminster seat.
Labour and the Brexit Party have jostled for position as the bookmakers’ favourite.
Labour’s by-election candidate, Unite activist Lisa Forbes, faced controversy in the week before the poll over a Facebook post she “liked” which said Theresa May has a “Zionist slave masters agenda”.
She told The Sunday Times she apologised “wholeheartedly for not calling out these posts” and that she had liked the video attached to the post, “not the views expressed in the accompanying text”.
She said she would “deepen” her “understanding of anti-Semitism so I can act as an ally, challenging it wherever it occurs”.
