In pictures: Sinatra gets intimate

Photographer Bob Willoughby has produced a selection of unseen images of US film legend Frank Sinatra, who he met on the set of From Here To Eternity in 1953.

Willoughby went on to become a trusted friend, and his London exhibition of pictures features more than 170 images, many of which have never been published before.
