In April Jon Cruddas MP and Abena Oppong-Asare MP sent a joint letter to Sadiq Khan, urging him to launch a Judicial Review into the Government's approval of a second waste incinerator in Belvedere. On Thursday 21 May, the deadline for a legal challenge, the Mayor of London tweeted:
"London does not need more waste-burning incinerators. I have challenged the Secretary of State's decision on the Cory Incinerator & have issued a claim to the planning court requesting a judicial review of that decision. We need to build the greener future our city deserves."
