Labour faces a tough battle to retain its seat in Copeland, with the Conservatives tipped to win what would be an historic victory in Thursday's by-election.
The Cumbrian constituency has remained a Labour stronghold for almost 80 years.
But the resignation of MP Jamie Reed, who has taken up a role at the Sellafield nuclear plant, means Jeremy Corbyn now faces one of his greatest tests as Labour leader.
Some 62% in the town voted to leave the European Union.

Theresa May has repeatedly dodged a question about maternity services on the campaign trail for the upcoming by-election in Copeland.
She was asked specifically about concerns which her own candidate, Trudy Harrison, has about maternity services closing at West Cumberland Hospital.
Harrison has said she is opposed to plans to close the unit, and May refused to answer the question four times.
