Kim Leadbeater, most agree, is brave to stand in the seat of Batley and Spen - but that alone may not guarantee her victory.

She's fending off a challenge from Tory candidate Ryan Stephenson and could also lose votes to the former Labour MP George Galloway, who is now standing for the Workers Party of Britain.

It would be a painful result for Labour leader Sir Keir Starmer - but not necessarily unexpected.

He’s already pledged to fight on whatever the result.
