Caffell, renowned for his platinum printing technique and for his work with Sir Paul and his late wife Linda, also denies sexually abusing her during the sessions.

The dad-of-three, who is also friends with David Bailey, now faces 12 charges rather than 18 after the judge cleared him of allegations relating to another girl. The court trial continues.
