Swansea Labour has been devastated by the death of Sybil Crouch.
Cllr Crouch had represented the Castle ward since 2012, and she was head of cultural services where she managed the Taliesin Arts Centre. She was also a former chairwoman of the Arts Council for Wales.
She was married to fellow Castle ward councillor and former leader of Swansea Council David Phillips.
Swansea Council leader Rob Stewart said: “I was extremely sad to hear about the passing of Sybil.
“Despite being ill for many months, she faced her illness with determination and bravery, and continued to work for her community.
“She was a passionate campaigner and dedicated, hard-working, councillor and advocate for Castle ward and Swansea.
“She was a huge supporter of the arts in Swansea, and made a significant contribution to our cultural sector through her work as a councillor, but also in her work at the university.
“Councillor Crouch will be sadly missed by all.”
