Campaigners have won a Court of Appeal ruling over controversial plans for a third runway at Heathrow Airport on environmental grounds.

Giving their ruling on Thursday, Lords Justice Lindblom, Singh and Haddon-Cave said the Government did not take enough account of its commitment to the Paris Agreement on climate change when setting out its support for the proposals in its National Policy Statement (NPS).

In a summary of the ruling, Lord Justice Lindblom told a packed court: "The Paris Agreement ought to have been taken into account by the Secretary of State in the preparation of the NPS and an explanation given as to how it was taken into account, but it was not."

Mayor of London Sadiq Khan, who supported the legal action, welcomed the decision.

He said: "We won. Today we blocked the Tory government plans to build a third runway at Heathrow Airport. Today's judgment is a major victory for all Londoners who are passionate about tackling the climate emergency and cleaning up our air."
