Where do the mayoral candidates stand?

Whether the expansion of the ULEZ goes ahead in October 2021 is in the hands of the Mayor of London. The current Mayor and architect of the proposed expansion is Sadiq Khan (Labour). He is up for re-election in May 2021.

What do those standing against him have to say about the proposed expansion?

Sadiq Khan

Labour Party Candidate, Sadiq Khan implemented the Central London ULEZ (as the T-Charge) in 2018. He is the architect of the wider ULEZ, which he wanted to bring in in 2020. In response to the consultation on ULEZ, many Labour Councils supported calls for the restrictions to extend to the whole of London.

Shaun Bailey

The Conservatives held the Mayoralty between 2008 and 2016 and Shaun Bailey is the main challenger to Labour’s candidate, current Mayor, Sadiq Khan. Together with the Conservative London Assembly Members, he opposes the planned expansion in 2021.

Sian Berry

Supports the expansion planned for 2021, but thinks it should go further, covering all of London. The Green Party has also called for the sale of all new petrol and diesel cars and vans to be banned by 2030.


The Ultra-Low Emission Zone is a scheme implemented by London Mayor, Sadiq Khan, based on an original proposal from Boris Johnson when he was Mayor. It currently operates in the central London Congestion Charge area for all vehicles.

The campaign is being run by 3RD PARTY LTD. A registered third party with the Electoral Commission (PEF number 10354) and also registered with the ICO as a data controller.
