A legal challenge led by rival councils against London Mayor Sadiq Khan’s decision to expand the ultra-low emission zone (ULEZ) around the capital has been authorised by the High Court.

Khan has announced plans to extend the ULEZ, which imposes a charge on drivers of vehicles that do not meet certain emissions standards, to cover the entire city by 2023.
