A: A Coroner investigates sudden or unexplained death in England, Wales and Northern Ireland and every county has to appoint one or more Coroners who are experienced doctors or lawyers. A death occurring in these circumstances is usually reported to the Coroner by the police or by a doctor. Sometimes this is done by the Registrar. If the death is not due to natural causes the Coroner is obliged by law to hold an inquest.
NB. The Procurator Fiscal carries out similar duties in Scotland.
