Mayor of London and London Assembly Elections 2021

Elections for the Mayor of London and London Assembly are being held on 6 May 2021.

These elections were originally due to take place last year (May 2020) however were postponed due to the COVID-19 pandemic.

Recent media reports have raised questions as to whether, given COVID-19, the Greater London Authority elections should take place on 6 May as scheduled.

To date, the Government has said the elections will go ahead, but it is keeping this under review. Brent is therefore continuing with its preparations for elections on 6 May. In addition, we are working with both the Electoral Commission and the Greater London Authority to ensure appropriate steps are taken to ensure that both voters and staff can safely work and participate in these polls.

A new law is now in force which allows electors who are unable to vote because they are self-isolating to vote by emergency proxy. A proxy vote is where you ask someone you trust to vote on your behalf. Voters will be able to apply for the emergency proxy up until 5pm on the day of the poll on Thursday 6 May and will not need to provide additional evidence to support their application.

The deadline to apply for a non-emergency proxy vote in time for the May elections is 5pm on Tuesday 27 April.

The different ways you can vote

There are three ways you can vote in the Mayor of London and London Assembly elections: in person at a polling station, by post or by proxy.

In person at a polling station

Before polling day you will be sent a poll card which will include details of where your polling station is. You do not need to take the poll card with you to vote, but it will help polling station staff find your address on the voting register.

When you arrive at the polling station you will be asked for your name and address. Staff will check you are on the register and then give you three ballot papers. Staff can also help you understand how to fill them out.

By post

Voting by post is an easy and convenient way of voting if you do not want to vote in person at a polling station.

By proxy

If you’re unable to vote in person you can ask someone to vote on your behalf. This is called a proxy vote.
