The Archbishops of Canterbury and York, and the Bishops of London, Durham and Winchester always have seats in the House of Lords. Twenty-one of the remaining Diocesan Bishops also sit in the Upper House, and they do so according to their dates of seniority. When a vacancy arises, it is filled by the senior Diocesan Bishop without a seat, and the vacated See is placed at the foot of the list of those awaiting seats. Translation of a Bishop from one See to another does not affect his right to sit in the House of Lords.
The Bishop of Sodor and Man and the Bishop of Gibraltar in Europe are not eligible to sit in the House of Lords, but the former has a seat in the Upper House of the Tynwald, Isle of Man.
