Gareth Snell and Paul Nuttall are the favourites to win Stoke-on-Trent Central
Ukip ran Labour a close second during the last election, finishing just 5,179 votes behind the left-wingers.
The Express.co.uk has been told the result between Ukip and Labour is too close to call, however the Tories are expected to finish a “distant” third
Another Ukip source also told the Express.co.uk that Labour had just edged the Stoke by-election.
The weather was a help for the eurosceptic party but Labour’s superior amount of activists on the ground has helped them to get the vote out, a Ukip source has claimed.
Turnout in Stoke was officially announced as 38.1 per cent – higher than what experts predicted.
Labour have held Stoke-on-Trent Central since the seat was created in the 1950.
Paul Nuttall goes to vote in Stoke
Polling in Stoke closed at 10pm on Thursday and the results are due in around 3am on Friday morning.
Ukip will have been buoyed after a recent national poll found that Labour were the third choice party, behind the Tories and Ukip, among working class voters.
The by-election has been marred by a series of blunders in both the Ukip and Labour camps.
Labour’s pro-Remain candidate for Stoke, Gareth Snell, labelled Brexit a “pile of s***” following the referendum result.
Paul Nuttall has also been attacked after a post on his website claimed he had lost “close personal friend” in the Hillsborough disaster – something he admitted was not true during a live radio interview.
