The Lord Mayor performs numerous other functions, including serving as the Chief Magistrate of the City of London, Admiral of the Port of London, Rector of City, University of London, President of Gresham College, President of City of London Reserve Forces and Cadets Association, and Trustee of St Paul's Cathedral. The Lord Mayor also heads the City's Commission of Lieutenancy, which represents the Sovereign in the City of London (other counties usually have Lord Lieutenants, as opposed to Commissions), and annually attends the Treloar Trust (named after Sir William Treloar, Lord Mayor in 1906), in Hampshire. The Treloar Trust runs two educational sites for disabled children, a school and college.
