Comptroller of the Household
The Comptroller of the Household is a historical position in the British royal household, nominally the second-ranking member of the Lord Steward's department after the Treasurer of the Household. The Comptroller was an ex officio member of the Board of Green Cloth, until that body was abolished in the reform of local government licensing in 2004.
