Justin Welby, the Archbishop of Canterbury, has announced his resignation following a critical report on the Church of England's handling of abuse allegations against John Smyth.

The report criticized Welby, 68, for not reporting Smyth's abuse of boys and young men to police in 2013.

In his resignation statement, Welby expressed sorrow and took personal and institutional responsibility, stating that stepping down serves the Church's best interests.

Prime Minister Keir Starmer showed respect for Welby's decision, emphasizing concern for the abuse victims.

The report highlighted the Church's missed opportunities to hold Smyth accountable, allowing his abuse to continue until his death in 2018.

Smyth, a barrister and lay preacher, allegedly abused up to 30 boys at summer camps in the UK during the 1970s and 1980s and later abused more children in Zimbabwe and South Africa.

Welby, ordained in 1992, served in various roles before becoming Archbishop in 2013, where he led 85 million Anglicans globally.

During his tenure, he addressed political and social issues, such as payday lending and immigration reform.

His resignation comes as the Church faces ongoing challenges on safeguarding and leadership changes.

Searching for Welby's successor is expected to last at least six months.

The Archbishop of York, Stephen Cottrell, noted progress in safeguarding under Welby's leadership but acknowledged further work is needed.

Survivors and church members have called for more resignations to enhance accountability.

Welby's legacy includes advocating for women's ordination and racial justice, despite leaving the Church smaller and divided.

The Church aims to instigate cultural change and ensure a safer environment for all its members.
