In the event of a candidate dying, there is no provision for the poll to be cancelled.
If a candidate on a party list dies, the party list will be unaffected, except that the Greater London Returning Officer (GLRO) will remove the deceased candidate’s name from the party list.1
Death occurred after declaration of results
If an already elected candidate dies after the declaration of the result, the procedure to be followed will depend on whether they were a party list or an independent candidate.
Party list candidate
the next person on the party’s list will be invited by the GLRO to replace the deceased member.
Individual candidate
the vacancy will remain unfilled until the next ordinary election.
