A map reveals where Heathrow will expand after the government gave a green light to the airport’s growth. The UK’s busiest airport is expected to get a third runway after confirmation by Chancellor Rachel Reeves today.

British finance minister Rachel Reeves is expected to back the expansion of Heathrow Airport on Wednesday, turning to the country's most controversial infrastructure project in her hunt for economic growth.

What could a third runway at Heathrow mean for tourism and the climate? Whatever the outcome, it’s still a long way away from happening.

It is the rich and the corporations who will take the lion’s share of the benefits from Labour’s and all airport expansions, while the poorest around the world pay the costs.

The third runway is part of its drive to lift the U.K. economy out of a long period of stagnation, Treasury chief Rachel Reeves said in a speech on Wednesday.
