The Lords Spiritual are the twenty-six bishops of the Church of England who sit in the House of Lords of the Parliament of the United Kingdom.
The archbishop of Canterbury, archbishop of York, and the bishops of London, Durham, and Winchester are always Lords Spiritual. The remaining twenty-one Lords Spiritual are typically appointed based on length of service alone, however the Lords Spiritual (Women) Act 2015, which is in force until 2030, gives female bishops priority in appointments. When a vacancy arises, if a woman is eligible to become a Lord Spiritual then she must be appointed, and if more than one woman is eligible then the appointment is decided on length of service.
