He retired from this position on 5 March 2010. In 2014, Butler was involved in the transition process for the new Diocese of Leeds as "mentor bishop"; he remains an honorary assistant bishop of that diocese. Early life and education Born in Birmingham, Butler attended King Edward VI Five Ways school in Birmingham and the University of Leeds, where he obtained a first class honours BSc, an MSc and PhD in electronics. He trained for ordination with the Mirfield Fathers at the College of the Resurrection in Yorkshire. Ordained ministry After ordination in 1964, he served three years as a curate in the Diocese of Ely and Diocese of Canterbury before spending 12 years as a lecturer in electronics and a chaplain at the University of Zambia and then at the University of Kent in Canterbury. During this period he was on the staff of Lusaka Cathedral and Canterbury Cathedral respectively. From 1980 to 1985, Butler was the Archdeacon of Northolt in the Diocese of London. Butler was consecrated as a bishop on 30 November 1985, by Robert Runcie, Archbishop of Canterbury, at St Paul's Cathedral, to become area Bishop of Willesden until he was appointed diocesan Bishop of Leicester in 1991 (his election was confirmed on 1 July) and translated to Southwark in 1998. Butler has been active at national and international level. Until 1995 he chaired the follow-up to "Faith in the City", which published the controversial "Staying in the City" report. He chaired the General Synod's Board of Mission from 1995 until 2001 and is now vice-chair Public Affairs of the Mission and Public Affairs Council. He is also Chair of the Governors of Ripon College, Cuddesdon.

Since mid-2003 the Bishop has represented the Church of England on the central committee of the World Council of Churches. He entered the House of Lords in 1997. Butler's beliefs were cited as the reason for some "valid but irregular" ordinations in his diocese.
