Gatwick Airport getting permission to operate a second runway would destroy Heathrow Airport’s arguments for needing an extra runway of their own, Sir Sadiq Khan suggested on Thursday.

The London mayor, who has said he is against any airport expansion due to the UK’s net zero carbon goals, said approval for a second Gatwick runway would represent a “slam dunk” against the rationale for expansion at Heathrow.
