A man lay dying at home waiting for paramedics as an ambulance waited outside a hospital for nearly five hours to drop off a patient, an inquest has heard.
Despite a fully-staffed ambulance service Fred Pring, 74, from Mynydd Isa, Flintshire, died 42 minutes after his wife, Joyce, had first called 999.
Mrs Pring wants the ambulance service to review its policies on 999 calls.
The coroner John Gittins will present his conclusions on Monday.
