Theroux shadows the Hamiltons

Theroux is now a constant at the side of the Hamiltons

TV presenter Louis Theroux is filming a BBC documentary on Neil and Christine Hamilton which has captured the drama of the rape allegations faced by the couple.

The BBC journalist went to Barkingside police station, east London, on Friday with the couple where they were quizzed by police.

He was present at the latest press conference held outside their Cheshire home on Monday, although he tried to keep himself out of shot of the news cameras.

The Hamiltons are happy to have Theroux follow them

Theroux, described by newspapers as "wacky", had already spent time with the Hamiltons for a new series of Louis Theroux Meets when the story broke.

At their invitation he is now continuing to follow them around, filming the aftermath of the sex allegations, which they have strenuously denied.

The BBC has confirmed the Hamiltons were already the subjects of the film before their arrest.

Other famous names who will feature in the new series, which starts at the end of the year, are shadow home secretary Ann Widdecombe and boxer Chris Eubank.

Excited

His previous subjects have included DJ Sir Jimmy Saville and magician Paul Daniels.

Mrs Hamilton has said she is excited at the prospect of Theroux of joining them at their Cheshire home.

She said: "The next bit of excitement is that Louis Theroux will be arriving shortly. He is coming up with us to spend a few days up there."

Theroux's name also cropped up during the couple's police interview.

Mrs Hamilton told investigators she had only heard of "swingers' parties" when Theroux had explained about them during an earlier encounter.

Theroux has declined to comment on the developments of the last few days, causing Mrs Hamilton to joke: "You little bashful one."

Theroux once memorably interviewed Sir Jimmy Saville

Theroux, the son of the travel writer and novelist Paul Theroux, is known for his revealing interviews with eccentric characters.

These were showcased in his series Weird Weekends including his meetings with such groups as white supremacists, professional wrestlers and pornographic stars.

He then branched out into spending time with celebrities, who allow him to follow them around for extended periods, leaving no area of their lives untouched.

Earlier this year, Theroux picked up the Richard Dimbleby Award for best presenter at the Baftas, for his BBC Two series Weird Weekends.

The BBC is to re-run Christine Hamilton's chat show series.

The programmes will be screened at midnight on digital channel BBC Choice throughout the week.

Among those she spoke to were James Hewitt, Jonathan Aitken, Bernard Manning and former MP Piers Merchant.

A spokesman for BBC Choice said: "Now is the perfect time to give a repeat airing to this show.

"Christine talked in-depth to some of the most controversial and infamous public figures in the UK about how they survived low-points in their careers, and how they planned to rebuild them.

"Current circumstances make its contents particularly relevant once more."
