Sir William Lucy

The Sheriff is the oldest secular office under the Crown. Formerly the High Sheriff was the principal law enforcement officer in the county but over the centuries most of the responsibilities associated with the post have been transferred elsewhere or are now defunct, so that its functions are now largely ceremonial. The High Sheriff changes every March. Under the provisions of the Local Government Act 1972, on 1 April 1974 the office previously known as Sheriff was retitled High Sheriff.

For a period prior to the middle of the 16th century the Sheriff of Warwickshire was also the Sheriff of Leicestershire.
