It’s thought Chancellor, Rachel Reeves will use a speech on economic growth to reveal plans for a controversial third runway at the airport.
Expansion at Gatwick and Luton airports are also on the cards even though MPs have asked for more time to assess noise pollution.
Robert Barnstone from the No 3rd Runway Coalition says expansion is in direct conflict with the Government’s net zero carbon target.
Rachel Reeves is due to speak at 10am.
