Voters will head to the polls in Chester today to decide the city's new MP in a by-election triggered by the resignation of Labour's Christian Matheson.
Last month Mr Matheson quit the Commons and was suspended from the party over "serious" sexual misconduct.
Today's vote will be the first by-election since June where the Tories suffered a historic defeat in the Devon seat of Tiverton and Honiton - despite a 24,000-strong majority - to the Liberal Democrats.
