Tellers are people who stand outside polling places and record the elector numbers of electors who have voted. They can then identify likely supporters who have not voted and encourage them to vote before the close of poll.
Tellers have no legal status and voters can refuse to give information to them. The (Acting) Returning Officer is in charge of the conduct of the election. If they are concerned by the activities of tellers, they can ask tellers to comply with agreed behaviour or leave the polling place.
We have produced a factsheet of tellers’ dos and don’ts, as well as more comprehensive guidance on the activities of tellers. The guidance aims to ensure that everyone knows precisely what is and is not acceptable and is designed to promote appropriate standards of conduct. The (Acting) Returning Officer may also provide their own version of guidance to tellers.
