Some offices are put into ‘commission’; that is, multiple commissioners are appointed to collectively exercise the office. The office of Lord High Treasurer has been in commission since 1612, although not filled continuously until 1714: the First Lord of the Treasury is the Prime Minister, the Second Lord is the Chancellor of the Exchequer, and the remaining Lords Commissioners are Government Whips. The office of Lord High Admiral was for many years also in commission, but merged with the crown in 1964 and is now an honorary appointment in the gift of the reigning monarch. Prince Philip, Duke of Edinburgh (consort of the current monarch) was granted the title on his 90th birthday. The remaining officers became governmental officers: Lord Chancellor, Lord President and Lord Privy Seal are appointed by the Crown on the advice of the Prime Minister. The Lord Chancellor is Secretary of State for Justice; the posts of Lord President and Lord Privy Seal are normally each combined with a cabinet postcurrently Leader of the House of Commons and Leader of the House of Lords, respectively — they are a device by which cabinet members with these (or other) unpaid posts are paid a salary and given precedence.
