Jimmy Savile's long-time producer on children's TV show Jim'll Fix It has said he was completely unaware of the presenter's activities and said the star managed to "hoodwink" him.
But Roger Ordish said he did know that Savile had a "predilection for younger females".
In his first interview since the disclosures about Savile's alleged abuse of possibly dozens of under-age victims over a period of many years, he described the presenter as a "manipulative" man.
But he told ITV1's This Morning he saw no abuse during the two decades in which he worked with the late TV and radio host.
"I didn't see anything and nothing was reported to me," he said. During their years working together, Mr Ordish said Savile, whom he described as a private man who "compartmentalised" different areas of his life, even stayed at his home.
"He slept in a bedroom next to my 14-year-old daughter and I hope that is some indication that we had no suspicions of anything of this nature at all," he said.
The disclosures about Savile's private life were made in an ITV documentary a fortnight ago which had dismayed Mr Ordish. He said of the Exposure documentary: "I was absolutely shocked and shattered and I was surprised that I had not been approached by the programme."
He maintained he knew nothing about Savile's activities, although he told This Morning hosts Phillip Schofield and Holly Willoughby there had been rumours.
But he went on: "You hear rumours about everybody famous, there must be rumours that go around about you two. We were aware that Jim had a predilection for younger females," he added, saying it was obvious from the way he chatted to girls.
Mr Ordish said Savile would compliment them on their beauty, "but nothing obscene", adding: "These are girls who are young females, they're not children. they could have been 14 looking like 18, but they were not children in my definition of the word."
