CAMPAIGNERS lost a High Court challenge today against the government’s decision to approve the Sizewell C nuclear power plant.

Together Against Sizewell C (Tasc) launched a bid to challenge development consent granted for the multibillion-pound project in Suffolk by then business secretary Kwasi Kwarteng in July 2022.

At a hearing in March, lawyers for the group of local residents argued the government failed to assess possible environmental impacts, including the impact of providing an “essential” water supply to the project.
