 The Lords Spiritual can now number no more than 26; these are the Archbishop of Canterbury, the Archbishop of York, the Bishop of London, the Bishop of Durham, the Bishop of Winchester (who sit by right regardless of seniority) and the 21 longest-serving bishops from other dioceses in the Church of England (excluding the dioceses of Sodor and Man and Gibraltar in Europe, as these lie entirely outside the United Kingdom).Following a change to the law in 2014 to allow women to be ordained bishops, the Lords Spiritual (Women) Act 2015 was passed, which provides that whenever a vacancy arises among the Lords Spiritual during the ten years following the Act coming into force, the vacancy has to be filled by a woman, if one is eligible.This does not apply to the five bishops who sit by right.
