A prolocutor is a chairman of some ecclesiastical assemblies in Anglicanism. In the Church of England, the prolocutor is chairman of the lower house of the Convocations of Canterbury and York, the House of Clergy. He presides in that house and acts as representative and spokesman in the upper house. He is elected by the lower house for a period of five years at the beginning of each quinquennium of the General Synod of the Church of England. The term means one who speaks for others (Lat. pro, for, and loqui, to speak). Following the inauguration of the General Synod in 2015, Canon Simon Butler was elected as the Prolocutor of the Lower House of the Convocation of Canterbury. The Venerable Cherry Vann was elected as Prolocutor of the Lower House of the Convocation of York.
