LABOUR’S economic growth plans hit fresh turbulence today as Chancellor Rachel Reeves announced government backing for a third runway at Heathrow Airport.

The move, which appears to fly in the face of Labour’s climate commitments, was opposed by a range of politicians and environmental campaigners, although welcomed by some trade unions.

Ms Reeves also announced state support for an Oxford-Cambridge “growth arc” and for investment in Manchester’s Old Trafford area.
