The government has approved a third runway at Heathrow to expand UK airport capacity.
Ministers approved the long-awaited decision at a cabinet committee meeting on Tuesday.
Transport Secretary Chris Grayling called the decision “truly momentous” and said expansion would improve the UK’s connections with the rest of the world and support trade and jobs.
He will make a statement to the House of Commons about 13:00.
Both unions and business groups welcomed the decision to expand Heathrow. TUC general secretary Frances O’Grady said it was “absolutely vital for Britain”, while CBI chief Paul Drechsler said it would create jobs and boost economic growth.
Heathrow management said the airport was ready to deliver a third runway that was “fair, affordable and secures the benefits of expansion for the whole of the UK”.
However, Sadiq Khan, the mayor of London, said it was the wrong decision for both London and the UK.
Expanding airport capacity in the South East of England has been a political hot potato for many years.
Although Heathrow has always been the favourite among businesses, it has attracted the most opposition from MPs with constituencies near the airport or under flight paths.
Zac Goldsmith, the Tory MP for Richmond Park who has threatened to resign if Heathrow expansion was approved, called the announcement “catastrophic” and said he would meet his constituents before making a statement later on Tuesday.
