List of deaths of candidates during general elections of the United Kingdom
The rules governing the procedure for dealing with the death of a candidate occur in the Representation of the People Act 1983. Unless the deceased candidate was standing as an independent, their death results in the election being postponed whether it is a general election or a by-election. The poll is stopped immediately even if voting has closed and the votes are being counted, unless the death occurs after the declaration of the result.
The Returning Officer must be shown proof of the death; a new election is then arranged for 28 days after this date. The time at which the Returning Officer hears of the death is the relevant factor not the date of the death itself. There is no requirement for other nominated candidates to re-register, a new candidate may be nominated by the party of the deceased and any of the other candidates may at this point withdraw from the election, but independent candidates and candidates for other parties cannot be nominated.
According to the Electoral Commission, if the deceased candidate was standing as an independent, the election continues as normal. The Speaker of the House of Commons seeking re-election is treated effectively as if he were standing for a party, except that in this case other candidates may be nominated by any party or as independents as the proceedings begin afresh. 
Under all circumstances the deposit will be returned to the estate of the deceased candidate. In the unlikely event that a deceased independent candidate wins, the election is re-held with no new candidates and all deposits are returned. If it is a tie between a deceased independent candidate and one or more living candidates, the deceased candidate is ignored.
The most recent candidate to die during a general election is former Eurovision singer Ronnie Carroll, who was standing in the Hampstead and Kilburn constituency as an independent, who died on 13 April 2015. As he was an independent, the poll is not cancelled and will proceed with his name on the ballot paper. If he wins posthumously, a by-election will be held.
