Plans to expand London's other airports are already further along than Heathrow's and have in the past been viewed as an alternative to a third Heathrow runway. Work is set to start this year to expand capacity at Stansted's terminal. The government is due to make a decision on Gatwick airport by 27 February.

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.

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.

U.K. Treasury chief Rachel Reeves says that the new Labour government is backing the construction of third runway at London’s Heathrow Airport.

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.

Rachel Reeves confirmed plans for a third runway at London Heathrow Airport this morning, (Wednesday, January 29). The ambitious project has been backed by the airport itself, claiming it is the 'bold, responsible vision the UK needs to thrive in the 21st century'.

Britain's Labour government will back plans for a third runway at London's Heathrow Airport, finance minister Rachel Reeves said on Wednesday, saying the project could create over 100,000 jobs. Reeves said in a speech that the case for a third runway at Heathrow - Britain's busiest hub - was stronger than ever and that it would help boost economic growth.
