Chief constable, in nearly all County police forces in the UK is the title of the principal uniformed officer in charge of the police. A prominent exception to this is the Metropolitan Police force of greater London, where in 1933 the rank was subordinated to that of Deputy Assistant Commissioner, and in 1946 renamed Deputy Commander.
Notable Chief Constables of the Metropolitan Police have included Frederick Porter Wensley, the first detective to rise to this rank from that of Police Constable, and Sir Norman Kendal.
