Residents at an Oxfordshire mobile home park have lost their homes and life savings after being bullied and threatened by the site owner, Witney MP David Cameron has told Parliament.

He said some vulnerable occupants of Thameside Court, near Northmoor in west Oxfordshire, had told him "chilling" accounts of being forced out of their property under harassment by Tom Hartley, who runs the park.

Resident Peter Mills, 75, said: "He's forced people to sell at knock-down prices. (Tom Hartley) talks about a small minority of troublemakers, there's 61 occupied houses on this site and at the moment 48 of those belong to the residents' association, and this is how most of the residents feel."

Mr Mills said a meeting of residents packed Northmoor Village Hall in September, and two petitions have been raised asking for a meeting with Mr Hartley to discuss park rules.

During a special debate in Parliament on Tuesday, Mr Cameron urged the Government to protect the rights of residents of mobile home parks and quoted testimony he had collected from people at Thameside Court.

He said in one case an elderly couple wanted to sell their mobile home plot for £70,000, but after coming under "enormous pressure" from Mr Hartley, they eventually agreed to a deal worth just £20,000. Their plot was then put up for resale with a £90,000 price tag -- potentially netting the landowner £70,000 profit.

Mr Cameron said there were too many instances of "improper pressure" being applied to force home prices far below market value.

He said: "The stories they have told me are really quite chilling. Some people have lost their life savings -- they are bitter about this and I'm angry on their behalf."

According to the MP, Mr Hartley decreed a change in park rules, introducing a ban on children, outlawing residents under the age of 50 and stopped For Sale signs being put up.

Although such moves are not allowed under national park guidelines, the tactic makes mobile homes unsaleable at full market prices, freeing the park owner to scoop bargain properties for resale.

Mr Hartley, who has offices in Derbyshire, also came under fire for refusing to meet the Thameside Court resident's association, which represents the 60 mobile dwellers.

Mr Cameron said a meeting had now been arranged.

Mr Hartley said claims he had used improper pressure to force house prices below market value were "absolutely not true."

He added: "There's no ban on children in the park, that's not true, Thameside Park is run in accordance with the 1983 Mobile Homes Act.

"David Cameron said that 90 per cent of people in the park feel like this, which is not true in today's park.

"We've done our own survey and 90 per cent of the park are very happy and grateful for the progress in the last 12 months."
