Voters who have a postal vote will shortly be receiving their ballot papers, and almost one fifth of Londoners will have the chance to choose their next Mayor before May 5. Making sure people use their vote is the most important thing we can do before May 5, and we need your help to do it.
We'll be speaking to Labour voters in your area, encouraging them to use their votes for Labour. Can you spare a few hours to help?
Just sign up below and a local volunteer will be in touch with more information.
