Anti-expansion campaigners wearing Gordon Brown masks gathered in a Hounslow park on Saturday in one of the last shows of protest ahead of this month's expected decision on a third runway.
The stunt at Lampton Park, which is located directly under the flight path, brought together local and national groups to again highlight their opposition to all expansion at Heathrow.
The Government is expected to announce whether it intends to give BAA the green light to develop detailed plans for a third runway, a sixth terminal and the introduction on mixed-mode, which would allow planes to land all day long on the existing two runways, in the next few weeks.
Hounslow councillor Barbara Reid, speaking on behalf of the 2M group of local authorities opposed to expansion, said: "It is essential that Gordon Brown rules out mixed-mode as well as a third runway.
"Mixed-mode would be devastating for people living under the existing flight paths. It would mean all-day noise. It would mean an almost 50 per cent increase in the number of planes flying over our communities. It doesn't bear thinking about."
Meanwhile, Geraldine Nicholson, chair of NoTRAG (No Third Runway Action Group), which is fighting to stop the village of Sipson being razed to the ground, added: "We are fighting for the very survival of our communities that a third runway would destroy."
And John Stewart, chair of HACAN, said: "It's bad for the environment and most people don't buy Gordon Brown's line that it's needed for the health of the economy."
