LONDON (Reuters) - Archbishop of Canterbury Justin Welby, the spiritual leader of Anglicans worldwide and the head of the Church of England, will complete his official duties by January 6, after saying last week that he would quit over an abuse scandal.

Welby resigned after a report found that he had taken insufficient action to bring to justice one of the church's most prolific serial abusers - a British lawyer who subjected more than 100 boys and young men to "brutal and horrific" physical and sexual abuse over a 40-year period.
