Andrew Sachs has vowed never to watch Jonathan Ross again after his comeback, as it emerged his family has been torn apart by the phone prank scandal.

Comeback: Jonathan Ross films tonight's show

His wife, Melody, said it has destroyed the couple's relationship with their granddaughter Georgina Baillie, part of a dance group called Satanic Sluts. Ms Baillie, 23, was the focus of lewd messages left by Ross and Russell Brand on her grandfather's phone.

Mrs Sachs said they had not spoken to Georgina since the scandal broke three months ago and she sold her story to the press.

"I have no wish to speak to her," she added. "We didn't know any of this about the drugs, sex with Russell Brand and we had never heard the name Satanic Sluts. She used to be a lovely girl and we spent a lot of money on her, educating her."

Boycott: Andrew Sachs

Mr Sachs, 78, said he would watch Friday Night With Jonathan Ross tonight "out of curiosity", but added: "I don't want to see him after Friday.

"His show is embarrassing, it is not an interview show, it's the Jonathan Ross show. A lot of people like the show but I don't, and I'm not alone.

"His quickness of mind is worth retaining but with the good points go the bad ones maybe. It is extraordinary that a man of that experience allowed himself to be shown like that. It is just self-restraint he has not got."

The Fawlty Towers star was also scathing about Brand, who used clips of the offending recording in his stand-up comedy act. He said: "To make fun of all of this, he seems to be unwell. I don't want to say any more because it will give him extra ammunition."
