The Archbishop of Canterbury, spiritual leader of the Anglican Communion, has resigned over his handling of a sex abuse scandal.
An investigation found that Justin Welby failed to inform authorities about serial physical and sexual abuse.
Welby said that he was first informed of abuse allegations in 2013, when he was appointed Archbishop of Canterbury, the most senior leader of the Church of England. Welby said he was told the police had been notified.
He said he believed that an appropriate resolution would follow, but apologized for failing to ensure that the accusations were "energetically investigated."
According to a report released last week, John Smyth abused more than 100 boys and young men, beginning in the 1970s.
In a statement Welby said he "must take personal and institutional responsibility" for failing to properly report the abuse.
