When and where will count take place 

The verification of all three contests will take place on Friday 3 May 2024, followed by counting the votes on Saturday 4 May 2024. This may change if any unscheduled polls are due to take place on the same day.

The Constituency Returning Officer (CRO) or Greater London Returning Officer (GLRO) (as appropriate) will notify you of the exact time and location and will request that you provide a list of who will be attending with you. See our guidance on who can attend the count and appointing counting agents for more information. 

They will issue instructions or an invitation with any requirements they have in place for attendance. This could include information about any additional security measures in place such as requiring attendees to show ID and bag checks before being allowed entry, as well as information about the expected standards of behaviour for attendees. You should ensure these instructions are followed by yourself and anyone else attending with you. Failure to comply with these expectations, or any instructions issued by the CRO/GLRO, may result in your removal from the venue.

The Constituency Assembly member results will be announced at the relevant count venue. The Mayoral and London-wide Assembly member results will be announced at City Hall.
