Andy Burnham has reportedly reminded Labour MPs that he has historically opposed expanding Heathrow, casting uncertainty over his current position on a proposed third runway. The comments appear to contrast with the Government’s stated support for the project, which ministers say is justified by its economic benefits and potential to promote growth.

Heathrow Airport Limited wants permission to build a 3,500-metre runway, requiring the M25 to be diverted. Burnham has previously argued that expansion would worsen regional inequality, constrain aviation emissions and divert infrastructure spending towards London, while Heathrow says it would create jobs, support growth and reduce travel costs; the Government’s consultation on the expansion policy closed on 1 September.
