Heathrow's third runway gets go-ahead from Chris Grayling

Tory splits mean government may have to rely on Labour and SNP to win parliamentary vote

The government has finally given the green light to the plan to build a third runway at Heathrow after years of delays and opposition from campaigners.

The transport secretary, Chris Grayling, told MPs the announcement represented a "historic moment" that showed ministers had a clear vision to build "a Britain fit for the future". Critics claim it will damage the environment and could end up costing the taxpayer billions.
