The constituents of Stoke-on-Trent Central are set to go to the polls on Thursday to choose a new MP following the resignation of Labour’s Tristram Hunt.
Hunt, who quit in January, is taking up a post as director of the Victoria & Albert Museum in London.
Ukip leader Paul Nuttall is the highest-profile figure running for the seat, although Labour’s Gareth Snell is currently favourite to win.
Ukip came second in the constituency in the last general election with 7,041 votes to Labour’s 12,220.
The party will be hoping to capitalise on Stoke’s strong Brexit vote - the constituency recorded the highest proportion of those who voted to leave the European Union in the referendum.
