I don't think this guy was Savile's driver, this is somebody else. It says in the report that this case was unconnected to Savile. This guy was a BBC staff driver (I think).
Yes, he may have driven Savile, of course, but this chap was also in the news a few days ago so there may inevitably be some confusion.
