She said it kept her going and she was massively loved by all the cast and crew. "She was one of those rare people who didn't possess a grain of self pity and whose company always brightened your day. "A highly intelligent, joyful, talented and spectacularly spirited woman, who was an inspiration to us all." She added Ms Davies would be "unspeakably missed". Ms Davies had been a well-known face on TV screens since the 1970s, appearing in shows including The Forsyte Saga, The Bill, Upstairs, Downstairs, Grange Hill and Whitechapel.

Kelly Andrews, part of the team who represented Ms Davies for about 20 years, said: "She was extremely professional, but she was extraordinary fun and joyous to be around. "She saw the best in everyone. She wasn't just an actress but an activist - she really cared about it."
