John Richard Allan Llewellin (born 30 September 1938) is a retired Anglican bishop in the Church of England.
After serving a second curacy at Johannesburg Cathedral, and being expelled from South Africa by the apartheid Nationalist government of the day in 1971, he was then successively the Vicar of Waltham Cross, the Rector of Harpenden[9] and a canon of Truro Cathedral and ordained to the episcopate as the suffragan Bishop of St Germans (1985–92).
He was consecrated a bishop by Robert Runcie, Archbishop of Canterbury, on All Saints' Day 1985 (1 November) at Westminster Abbey.
While serving as Bishop of Dover he was appointed an honorary fellow of Canterbury Christ Church University.
[12] Llewellin was accused of failing to take appropriate action or to launch an investigation into General Synod member Jeremy Dowling in 1986.
