Voting is under way in the Holborn and St Pancras by-election as candidates from across the political spectrum vie to become its new MP.

About 30 polling stations - at churches and community centres - in the north London constituency opened at 07:00 BST and will close at 22:00, when a count will begin.

The seat became vacant after former prime minister Sir Keir Starmer announced he was standing down to focus on a role in international affairs.

Some 15 candidates are standing in the by-election, one of whom is an independent. 

Voters will need to show a form of acceptable ID - such as a driving licence or passport - to be able to vote.
