William Henry Mettam "Robin" Bailey (5 October 1919 – 14 January 1999) was an English actor. He was born in Hucknall, Nottinghamshire.Although often chosen for upper class and tradition-bound roles such as Mr Justice Graves in Thames Television's Rumpole of the Bailey, Bailey is perhaps most fondly remembered for his portrayal of Uncle Mort in I Didn't Know You Cared, the BBC's adaptation of Peter Tinniswood's stories about an extended Yorkshire family.
