Archbishop Justin Welby, who knew Smyth from Christian summer camps in the 1970s, was informed of abuse allegations in 2013 but failed to ensure they were thoroughly investigated, representing a missed opportunity to bring Smyth to justice.
The Makin Review found that Church officials knew about the abuse at the highest level since 1982 and participated in an active cover-up, allowing Smyth to continue abusing victims in Zimbabwe and South Africa until his death in 2018.
