Hundreds of campaigners, including some from Warwickshire and Staffordshire, gathered outside Parliament to protest against Government plans to build eco-towns in their areas.
Mike Brain, a councillor in Stratford-upon-Avon District Council, warned the Government the eco-towns would become the rural ghettoes of the future.
He said plans to build 6,000 houses in a scheme at Middle Quinton, Long Marston, was inappropriate for an area with no unemployment, very little housing needs and where it went against local planning policy.
And he accused the Government of choosing the site for financial gain, saying the Ministry of Defence land would earn the Government up to £200m if it was developed.
On the last day of the first phase of consultation on the eco-town scheme, the protesters gathered in Westminster chanting noisily and waving placards against the schemes which have been shortlisted for further consideration.
Tony Henman, father of tennis star Tim Henman, who is opposing a development close to his village Weston-on-the-Green, Oxfordshire, was among the campaigners.
He said: "The message we want to convey is that we're certainly in favour of new, affordable housing but it's got to be in the right place."
He said that if the scheme went ahead at Weston Otmoor, thousands of homes would be built on greenbelt and greenfield land, destroying the rural community and increasing traffic.
The protest came as the Conservatives announced they were withdrawing support for what they described as an "eco-con".
Shadow housing minister Grant Shapps said the Government was watering down the environmental standards for the construction of the towns and ignoring the needs of local communities. He said while he supported the idea that housing should be sustainable, it was important to work with people, not against them, in order to get the housing the country needed.
Mr Shapps said: "So-called eco-towns have become an eco-con mired in controversy and utterly discredited. We cannot support a scheme that's been exposed as a green sham and won't come even remotely near to building large numbers of eco-friendly homes."
Protesters against nine of the 15 shortlisted schemes, from which up to 10 successful bids will be chosen later in the year, were in Westminster to protest and hand in petitions at 10 Downing Street.
A number of MPs were also at the protest, including Michael Fabricant, from Lichfield, who said there was "nothing particularly eco" about the proposal to build a new settlement near Fradley, Staffordshire.
"There is no infrastructure provided, the road system is going to be clogged up and even the Government's own eco-panel has said that this town will be eco-unfriendly.
"It's completely wrong that local government is being ridden roughshod over by the centralist government saying there should be this town in Curborough which will be totally eco-unfriendly.
"I don't think the Government can have any doubt that there are good sound reasons to oppose this eco-town. If they're really listening, they'll stop this nonsense straight away," he said.
A number of high profile figures have added their support to protests against the schemes, with actors Dame Judi Dench and John Nettles and author Jilly Cooper all opposing the development of Middle Quinton, near Long Marston, in Stratford-upon-Avon.
But housing minister Caroline Flint said those who could "shout loudest" should not dominate the debate - and produced research showing more voters in favour of eco-towns than against.
A YouGov poll found 46% in support (10% strongly) and just 9% opposed, although more than a third (34%) offered no opinion either way.
Support dropped to 34% when people were asked if they would back an eco-town within five miles of their own home - with 15% objecting.
