He is the champion of ingratiating himself with unwary celebrities. But Louis Theroux may have met his match in Chris Eubank last night.

Few will have been disappointed at the former boxer's knockout performance in the BBC Two documentary, When Louis Met Chris Eubank.

Eubank, 35, of Upper Drive, Hove, said: "Anything like this is good television because I have a lot happening I suppose. I do quite a lot around the country for charities and schools and I'm not the most boring person in the world."

He was looking forward to watching the show with wife Karron and their four young children. But the former world champion was slightly miffed at what got left out. He is already hoping the BBC can be persuaded to make a second documentary from the material available.

He said: "We shot about 40 hours of film and it was cut down to 50 minutes.

"That 50 minutes has really harnessed me. We had a lot of fun but it doesn't show that."

According to Eubank, choice selections not seen included a push scooter race with Theroux down Regent Street and a poetry recital.

Theroux, an award-winning journalist, spent ten days with Eubank at his opulent £2 million mansion in Hove.

He met his children, watched Eubank being "savaged" by the panel on They Think It's All Over, went shopping and even got into the ring with the champ.

In the process, the wily journalist tried to find out what made his subject tick.

A visit to Eubank's London outfitter was revealing, particularly when his tailor suggested there might be a touch of the show-off in his dress sense. Eubank, in reply, said: "We prefer to use the word showmanship."

Later, Eubank told Theroux: "I aspire to talk like Prince Charles. It's very stylish."

Other fascinating moments included Eubank scootering around the dreary corridors of the BBC and explaining his relationship with Karron.

Asked what she got from the marriage, he said: "She's a mother, I'm her husband, she's my wife - we are together. We are in love. I fancy her."

But what about her?

Eubank paused and said: "She fancies me, too."

Their relationship, he said, was an old-fashioned one. He went out to work and she looked after the children.

Theroux commented: "There was a pattern in the Eubank household, with Chris looking after himself and Karron looking after everyone else."

For her part, Mrs Eubank told Theroux her husband, like most men, didn't help around the house.

She said: "I don't mind telling the world that."

However, Eubank said he gave his children 80 per cent more than his own father had given him.

Eubank's seven-tonne truck, immaculate, if eccentric, dress sense and habit of handing out signed postcards, makes him a documentary-maker's dream. Theroux is renowned for worming his way into confidences to extract the unseen sides of his subjects and gain embarrassing revelations.

The problem, as Eubank quickly admitted, was that he had nothing to hide.

He told our reporter: "I'm a very honest person. I don't use drugs, I don't use alcohol, I don't use bad language or anything in the negative."
