The archbishop of Canterbury plays a central part in national ceremonies such as coronations; due to his high public profile, his opinions are often in demand by the news media. As spiritual leader of the Anglican Communion, the archbishop, although without legal authority outside England, is recognised by convention as primus inter pares ("first among equals") of all Anglican primates worldwide. Since 1867 he has convened more or less decennial meetings of worldwide Anglican bishops, the Lambeth Conferences. In the last two of these functions, he has an important ecumenical and interfaith role, speaking on behalf of Anglicans in England and worldwide. The archbishop's main residence is Lambeth Palace in the London Borough of Lambeth. He also has lodgings in the Old Palace, Canterbury, located beside Canterbury Cathedral, where the Chair of St Augustine sits. As holder of one of the "five great sees" (the others being York, London, Durham and Winchester), the archbishop of Canterbury is ex officio one of the Lords Spiritual of the House of Lords. He is one of the highest-ranking men in England and the highest ranking non-royal in the United Kingdom's order of precedence. Since Henry VIII broke with Rome, the archbishops of Canterbury have been selected by the English (British since the Act of Union in 1707) monarch. Since the 20th century, the appointment of archbishops of Canterbury conventionally alternates between Anglo-Catholics and Evangelicals. The current archbishop, Justin Welby, the 105th archbishop of Canterbury, was enthroned at Canterbury Cathedral on 4 February 2013. As archbishop he signs himself as + Justin Cantuar. His predecessor, Rowan Williams, 104th archbishop of Canterbury, was enthroned at Canterbury Cathedral on 27 February 2003. Immediately prior to his appointment to Canterbury, Williams was the bishop of Monmouth and archbishop of Wales. On 18 March 2012, Williams announced he would be stepping down as archbishop of Canterbury at the end of 2012 to become master of Magdalene College, Cambridge. Additional roles In addition to his office, the archbishop holds a number of other positions; for example, he is joint president of the Council of Christians and Jews in the United Kingdom. Some positions he formally holds ex officio and others virtually so (the incumbent of the day, although appointed personally, is appointed because of his office). Amongst these are: Chancellor of Canterbury Christ Church University Visitor for the following academic institutions: All Souls College, Oxford Selwyn College, Cambridge Merton
