 Because the House of Lords is excluded from financial matters by tradition confirmed by the Parliament Acts, the office is effectively limited to members of the House of Commons; apart from these occasions (see above) when the Lord Chief Justice of the King's Bench has acted as interim Chancellor the last peer to hold the office was Henry Booth, 1st Earl of Warrington (at that time only a Baron, Lord Delamer) from 9 April 1689 to 18 March 1690.The chancellor holds the formerly independent office of Master of the Mint as a subsidiary office.The Chancellor of the Exchequer has no official London residence as such but since 1828 in his role as Second Lord of the Treasury he lives in the Second Lord's official residence, No.
