What is a peer in parliament?

A peer in parliament refers to a member of the House of Lords in the United Kingdom, which is one of the two houses of Parliament. Peers are not elected; they are appointed, inherit their titles, or hold ecclesiastical positions, and they play a role in reviewing legislation, conducting debates, and providing expertise. The House of Lords serves to complement the House of Commons, offering a different perspective on laws and public policy. Peers can be life peers, bishops, or hereditary peers, each with distinct roles and privileges.
