Climate change protesters caused traffic chaos this morning as they parked a car across the Heathrow tunnel in protest of the proposed third runway.

A blue Volkswagen was draped in a banner reading ‘No new runways’. The protest began just before 8.30am.

Initially three cars had been parked across the tunnel, with three protesters locked inside one of them.

The drivers of two of the vehicles have been arrested for obstructing a highway.

Officers are still trying to remove the protesters locked in one of the cars.


The M4 approaching terminals 2 and 3 was completely gridlocked, with images emerging on Twitter of cars lining as far as the eye can see.

Transport for London Traffic News tweeted: “The Heathrow Tunnel (into the airport) is currently blocked due to in impromptu demonstration, traffic is slow on M4 Spur”


Metropolitan Police said: "A contra-flow is in place in the outbound tunnel to facilitate the movement of traffic around the blocked tunnel (which is now empty), but motorists are advised possible delays to their journey as this incident is dealt with."
