Constituency Returning Officers (CROs) are required by law to send out combined poll cards for the Mayor of London election, the London-wide Assembly Member election and the Constituency Assembly Member election as soon as practicable after the publication of the notice of election.1
In order to ensure that voters receive the same information at a similar time regardless of where they live in Greater London, you should liaise and agree with CROs on timings for the delivery of poll cards.
You can find more information on the production of poll cards in our guidance for CROs delivering GLA elections.
