Grayling to face legal action over Heathrow expansion plan

Four councils back move, claiming proposal will not survive 'independent, lawful and rational' scrutiny

The transport secretary, Chris Grayling, is facing a fresh headache over Heathrow as a group of councils confirmed they were planning legal action against expansion, just hours after MPs voted overwhelmingly to back a third runway.

In an embarrassing blow for Theresa May, Conservative-run Windsor and Maidenhead, the prime minister's own local council, suggested after Monday night's vote that it was seriously considering joining the judicial review.
