The First Lord of the Treasury is the head of the Lords Commissioners of the Treasury exercising the ancient office of Lord High Treasurer in the United Kingdom. Constitutional convention holds that the office of First Lord is held by the Prime Minister. The office is not the United Kingdom's finance minister; this role is instead held by the Chancellor of the Exchequer, who is the second lord of the Treasury.
