The Marquess of Blandford quit a reality TV show about being homeless after spending just two nights ‘on the street’.

The marquess, who is the eldest son of the Duke of Marlborough and is also known as Jamie Blandford, had agreed to sleep rough for ten nights in London for the BBC1 show Famous, Rich and Homeless.

But last night in the opening episode viewers saw him quit on the third day.

The Marquess also shouted at a Centrepoint charity worker and clashed with John Bird, the co-founder of the Big Issue who guided the five celebrity participants — former tennis player Annabel Croft, TV presenter Hardeep Singh Kohli, journalist Rosie Boycott and actor Bruce Jones — throughout filming last winter.

The peer, who has been jailed four times for drugs and driving offences, was filmed telling the charity worker: “I’m not going to make a fool of myself by lamping you in the ****ing mouth but if I see you again you’ll know it.”

The show is meant to raise awareness of homelessness.

The 53-year-old, who is a great-nephew of Winston Churchill, has two of his five properties in Chelsea but producers dropped him off without any money in Shoreditch, in the east of the capital.

“It’s an area I’m unfamiliar with,” he told the camera, “and it’s not an area I feel particularly safe with.”

He added: “It’s good to put oneself in a position that isn’t particularly comfortable.

“I don’t relish the prospect of sleeping on concrete. The Churchill family are pretty good in times of war, if this is my personal war with concrete, so be it.”

But he failed to honour the programme’s mission and instead left his sleeping bag in the car park of a five-star hotel on the first night and checked into one of the rooms. On the second night he agreed to continue filming if he could stay in a hotel room and then quit the following day when told he had to sleep rough.

Fellow participant Mr Singh Kohli said: “Good riddance to him.

“If he doesn't have the *******s to do it, he can **** off”.

On the programme Mr Bird called the Marquess obnoxious and accused him of behaving like Little Lord Fauntleroy, but told BBC Breakfast yesterday: “When I was on the streets I lied and cheated.

“I did all sorts of dastardly things, so even that is something we can learn about.

“The thing about homelessness is it does destroy all your civilisation, all your culture, and it reduces you into a very different person.”

The second episode of Famous, Rich and Homeless is screened tonight on BBC1.

THE Marquess of Blandford, full name Charles James Spencer-Churchill, was jailed for six months and given a three-and-a-half-year driving ban at Oxford Crown Court in September 2007 for a string of motoring offences careless driving, dangerous driving and criminal damage. Having battled drink and heroin addiction, he had already been jailed three times for driving and drugs offences and in 1993 he went on the run from police for five days. In 1994 he became the first person to be banned from taxis after admitting forgery and theft charges. That same year he was disowned by his father and will no longer inherit the Blenheim Palace estate. In 2000, he was cleared by a jury of shoplifting from Harvey Nichols in Knightsbridge.
