Guidance for Candidates and Agents at Greater London Authority elections

What if the vote on a ballot paper is not clear?

A ballot paper will not be counted if it:

  • is unmarked 
  • does not contain the official mark
  • contains votes for more than one candidate or party 
  • contains any mark or writing that can identify the voter
  • does not indicate the voter’s intention with certainty

The Constituency Returning Officer (CRO) must draw up a statement for each of the three elections in their constituency, showing the number of ballot papers rejected for these reasons.1

The CRO must mark the word “rejected” on any ballot paper that is rejected.2 They must add the words “rejection objected to” if a counting agent objects to the CRO’s decision.

If the voter’s intention is clear on a ballot paper and the voter cannot be identified by any mark or writing, it will not be void if a vote is marked:

  • elsewhere than in the proper place
  • by other means than a cross (e.g. a tick)
  • by more than one mark

Doubtful ballot papers

To assist CROs, we have produced guidance on how to adjudicate votes on ballot papers that may appear doubtful. This guidance is contained in our booklet Dealing with doubtful ballot papers 


The examples given are based on the election rules. 

Please note that while this provides guidance for CROs, each individual CRO has the ultimate responsibility for making a decision on individual ballot papers. Their decision to reject a particular ballot paper during the count or recount is final and can be reviewed only at an election petition after the declaration of the result. For more details see our guidance on election petitions.
