Fifteen candidates will be fighting for the Peterborough seat vacated by disgraced MP Fiona Onasanya.
The by-election, taking place on June 6, was triggered when constituents signed a recall petition demanding Ms Onasanya's removal.
The independent MP was jailed for perverting the course of justice, and is the first-ever to be removed by the recall process, introduced by David Cameron in 2015.
Last week, Ms Onasanya announced she would not stand in the by-election "in light of the recall result".
Around 19,261 people signed the petition, which is over 27 per cent of registered voters in the Peterborough area, and well above the 10 per cent threshold required for a recall.
And in the EU referendum, 61 per cent of people in the city voted to leave - which the pro-Brexit parties will be hoping to capitalise on.
So who will be fighting for the seat?
