Bishop of Leicester (suffragan) explained

The Bishop of Leicester was a suffragan bishop of the Church of England Diocese of Peterborough in the Province of Canterbury.

A thousand years after it had last been used (for a diocesan Mercian bishop, 679–888) the episcopal title was resurrected as a suffragan see within the diocese of Peterborough. The suffragan Bishop of Leicester assisted the diocesan Bishop of Peterborough in overseeing the diocese.^[1]

In the modern Diocese of Leicester, there was a stipendiary (paid) Assistant Bishop of Leicester (1987–2017), until a new suffragan See of Loughborough was erected to replace the Assistant Bishop role^[2] ^[3] — see Bishop of Loughborough.
