That is the members of the British House of Lords which is the second chamber of the United Kingdom Houses of Parliament.
Members of the House of Lords (also known as "peers"') consist of the;
- Lords Spiritual
- Lords Temporal
The Lords Spiritual are the senior bishops of the Church of England
. The Lords Temporal comprise the lay peers
(both hereditary and life peers) as well as the Law Lords
(that is the senior judges)
In the formal language of statutory legislation the phrase Lords Spiritual and Temporal is commonly, if not exclusively used, probably for no other reason than it sounds so much more impressive than simply writing, members of the House of Lords.
