Muriel Graham was the wife of Jimmy Graham, who had an affair with Rita Littlewood in September 1974. Muriel had a surprise meeting with Jimmy in a restaurant car park while he was with Rita, who he passed off as a client. Jimmy then went off with Muriel and their children, Robert and Pamela. Rita wasn't annoyed but seeing Jimmy with his family woke her up to the reality of splitting up a home and she broke off the affair later that day.
