A rift within the Labour Party has surfaced over reported plans by Rachel Reeves to approve a third runway at Heathrow and expand operations at Gatwick and Luton airports. While she emphasises economic growth as the Government’s priority, several high-profile Labour figures, including Greater Manchester mayor Andy Burnham and London mayor Sadiq Khan, have voiced strong opposition. Burnham argues that prioritising airport expansion in the South could hinder infrastructure investment in northern England and concentrate growth in London. Khan cites concerns about worsening air quality, increased noise, and the impact on London’s net-zero emissions target by 2030. Key Labour figures, including  Keir Starmer and Ed Miliband, spoke against Heathrow’s expansion while they were in opposition. Reeves has countered criticism by stating that Britain’s reluctance to approve major projects has stalled economic growth. The debate highlights tensions between economic ambitions and environmental sustainability within Labour’s leadership.
