Only United Kingdom government ministers can establish public inquiries, set their terms of reference, and appoint the chair.
Statutory public inquiries are led by a panel of professional people with a chairperson, who are often judges,[5] or a lord, professor, senior civil servant, scientist, doctor or engineer.
[11] Royal commissions were used so that the monarch could obtain advice and inquire into matters and misconduct outside of institutions, such as parliament.
[11] The first royal commission goes back to William the Conqueror in the 11th century, when he nominated an inquiry to produce the Domesday Book of land ownership.
[11] Royal commissions were later appointed by governments to obtain expert advice on subjects such as health, education, labour reform, public administration, welfare and factory legislation.
[17] Inquiries are usually held in local planning authority offices, village halls or community centres.
