If the Returning Officer (RO) is notified of a candidate’s death during the election campaign or even on polling day itself (but before the declaration of the result), the poll will be cancelled.1
The RO will in that case order a new election to fill the vacancy. The new polling day will be within 35 working days of the day fixed for the first election. 2
Candidates already validly nominated do not have to be nominated a second time.3
Should a fellow candidate die during the campaign, the RO will provide you with further guidance.
If an already elected candidate dies after the declaration of the result, a by-election would be needed to fill the vacancy.
