Cardiff and Vale University Health Board has apologised for "unacceptable" failings in the treatment of Ann Clwyd's late husband.
The Cynon Valley MP said Owen Roberts was treated like a "battery hen" before his death last year at the University Hospital of Wales.
A report into his care revealed he was kept on a trolley in the emergency department for 27 hours.
Parliamentary correspondent David Cornock reports.
