A senator for life is a member of the senate or equivalent upper chamber of a legislature who has life tenure. As of 2023, five Italian senators out of 205, two out of the 41 Burundian senators, one Congolese senator out of 109, and all members of the British House of Lords (apart from the 26 Lords Spiritual who are expected to retire at the age of 70) have lifetime tenure (although Lords can choose to resign or retire or can be expelled in cases of misconduct). Several South American countries once granted lifetime membership to former presidents but have since abolished the practice. Source: Wikipedia (en)
