"I am delighted at the appointment of the Right Reverend Justin Welby to Canterbury.
"I have had the privilege of working closely with him on various occasions and have always been enriched and encouraged by the experience.
"He has an extraordinary range of skills and is a person of grace, patience, wisdom and humour.
"He will bring to this office both a rich pastoral experience and a keen sense of international priorities, for Church and world.
