The U.K. House of Commons, in a 415-to-119 vote, approved expansion plans to build a third runway at London's Heathrow Airport, according to the BBC. The plan, which would increase the airport's capacity to 130 million passengers per year and make it the world's largest airport, has had support from the U.K.'s business community, including the Confederation of British Industry. CBI director-general Carolyn Fairbairn said the approval "will lift prosperity across the country and has long been seen as vital for firms, especially exporters." However, the expansion continues to face significant opposition due to environmental concerns, as well as taxpayer costs. The airport's plans could face judicial reviews from opponents and will require approval by the Planning Inspectorate. Construction is not slated to begin until 2021, according to the Financial Times.
