The chair of the S4C Authority has paid tribute to the actor Iola Gregory describing her as "one of the great names" of Welsh drama.
Huw Jones said, "It was with huge sadness that I learned of the death of Iola Gregory, one of the great names of Welsh language drama over the past 40 years. Whatever role she played, whether on stage, television or film, her presence would always be striking; a true sign of her natural ability to portray and create a character.
"For many, she will be best known for playing the colourful Jean McGurk - Mrs Mac - in Pobol y Cwm, but before this role, she had already made her mark in film and television, with prominent and memorable parts in productions such as Joni Jones, Minafon, Aderyn Papur, Rhosyn a Rhith/Coming up Roses and Stormydd Awst.
"More recently, she starred in the twice weekly Rownd a Rownd and the drama series Porthpenwaig but her career had started in the 1970s when she was among the pioneers of professional Welsh language theatre, being a founding member of Theatr Bara Caws in 1977.
"Her contribution to drama was immense, her commitment to the creative industries filled with passion, and her passing is a huge loss to us all."
