Former Archbishop of Canterbury Dr Rowan Williams has taken his seat in the House of Lords as a life peer.
Lord Williams of Oystermouth, who stepped down as Archbishop at the end of last year, swore his allegiance to the Queen in a short ceremony earlier today.
He became a member of the House of Lords when he was appointed to his position of Archbishop of Canterbury in 2002, and was nominated for a peerage by David Cameron after announcing his retirement from the role.
Lord Williams will sit as an independent crossbench peer.
Dr Rowan Williams has attended his last service as the Archbishop of Canterbury at the city's cathedral, before he leaves office as head of the Church of England and spiritual leader of the 77 million-strong Anglican Communion.
More than 700 people turned out to bid farewell to 62-year-old Dr Williams before he officially departs as the 104th Archbishop of Canterbury on New Year's Eve following a 10-year tenure.
He will go on to take up the posts of Master of Magdalene College, Cambridge, and chairman of the board of trustees of Christian Aid, the international development agency.
Dr Williams will be replaced by 56-year-old former oil executive the Rt Rev Justin Welby, the Bishop of Durham, who will be consecrated in March at Canterbury Cathedral as Archbishop of Canterbury.
