The program, to be shown Sunday, also shows Anderson making extraordinary allegations that Scotland Yard secretly and frequently uses private detectives to assist with investigations.
Hidden cameras film him claiming that the Met had approached him to uncover information that the police could not.
At one point, Anderson asked a Dispatches undercover reporter whether they were working for the Met. When questioned why he would ask that, Anderson replied: "We've had over the years, surprisingly or not surprisingly, quite a lot of requests from the police to do investigations."
He said that the police were governed by rigid processes that meant they sometimes needed to rely upon private investigators, and was recorded claiming: "The police have to follow a strict routine in order to investigate. You can't investigate someone without enough proof about their innocence or guilt. It's Catch-22. You can't get in there to look at people, but you can't find information out about them without getting in there and they have to hold back because there's no evidence. So someone gets approached [and is told]: 'Look, erm, we'd like some information on this person'."
When asked again if he had undertaken requests from Scotland Yard in the past, Anderson said: "Unofficially, and I wouldn't admit that, but yes."
The Met denied it ever used private investigators. A statement read "the Metropolitan Police Service does not use and has no need for such practices," adding that the force had never used Anderson or Crown Intelligence.
A statement by Anderson said that he acted "within the acceptable parameters of the profession" and "within the framework of the Data Protection Act". He added that the program's requests for data – on activists who the program said were intent on targeting a client – were acted upon in good faith and with a view to prevent and detect a crime being committed.
Anderson said all relevant information was obtained legally and denies any allegation of wrongdoing. He added that he was given the impression that all the information would be passed on to the clients "who were in discussion with the police with a view to preventing or detecting the commission of crime". He added that because Dispatches had received the consent of their volunteers to gather personal information, no offense had been committed under the Data Protection Act.
