The charges included sexually touching a one-year-old and encouraging one crazed groupie to abuse her own child during a sordid webcam chat on Skype.

Detectives successfully downloaded the recorded footage, 45 minutes long, in which Watkins talks about how they were going to use the baby for sex.

In the footage, which takes the form of a split screen, Watkins is seen to pleasure himself and refer to the woman and her baby as his “slave duo.”

The pair also discuss looking after the child as it grows up and making it have sex with animals and take drugs.

The child’s mother, speaking to Watkins, also refers to her baby as “your little fuck toy.”

At a later date she sent him a picture of herself having oral sex with the baby.

Mr Clee said that when police raided the home of Watkins following his arrest in September last year they also found a box of camcorder cassettes.

These proved to hold recordings of filmed sex acts with under age girl fans, one of whom he met up with in a New York hotel.

Mr Clee said that one girl, 16, contacted Watkins saying she was a fan who was still a virgin and went on to agree to give her virginity to him.

She then flew from Boston to New York and went to a hotel where he was staying, bringing with her a schoolgirl outfit he had asked her to dress in.

They are then filmed having oral and full sex before he asks her: “Do you like being my underage slut.”

Mr Clee added: “He finishes by urinating over her face and telling her to ‘drink my piss.’”

“Prosecuting QC Chris Clee gave details of a sickening plot to turn babies in subservient sex slaves using hard drugs.

Watkins and Woman A swapped messages where the frontman spoke of his sick desire to “make him mine” and to “cross the line”.

They also spoke of plans to blow crystal-meth smoke into the child’s face at a secret meet up in a Cardiff hotel.

And on March 23, Watkins sent the woman a message saying he wanted a “summer of filthy child porn” and how he wanted to take things “to the next level”.

Mr Clee also gave details of a sickening 17-minute video involving Watkins and Woman A.

Mr Clee said camcorder footage was shot in a London hotel room which showed Watkins perform a sex act on the child.
Computer analysts found the footage uploaded to online storage facility The Cloud.

Mr Clee said that following this meeting, the pair exchanged emails about how they would not go “easy” on the child next time.”
