An ex-BBC presenter has told a court he "stepped to one side" to let a young stranger engage in a public sex act with his wife because it "empowered" her.

Tony Wadsworth said his wife, Julie Wadsworth, was "a very special human being" who had found the daytime encounter with the male in woodland in the 1990s "exhilarating and exciting".

He added: "It was a positive, because she felt empowered as a woman.

"That it's not just me - the world and his wife can see the beautiful woman that she is."

The Wadsworths are on trial at Warwick Crown Court accused of encouraging boys to take part in sexual activity in Warwickshire woods between 1992 and 1996.
