Lawyers acting for a rival Heathrow Airport expansion project have launched a legal challenge to the plan voted in by MPs last month.
Sky News says it has seen a pre-action letter by lawyers acting for Heathrow Hub, which favours a cheaper scheme, which would extend one of the airport’s existing runways.
The letter, written by law firm DAC Beachcroft, claims ministers’ backing for a third runway was based on flawed information and analysis.
The pre-action letter ‘paves the way for it to seek a full judicial review of the Government’s decision’, according to Sky News, which adds the letter accuses the Department for Transport (DfT) of ‘failing to provide information about the Heathrow decision-making process sought under freedom of information laws’.
A separate judicial review process has already been set in motion by five London councils, supported by London mayor Sadiq Khan and Greenpeace.
The DfT has previously said it was "confident that our process for decision-making is robust and will strongly defend any challenges".
