The Vice-Chamberlain of the Household is a member of the Royal Household of the Sovereign of the United Kingdom.
 The office-holder is usually a junior government whip in the British House of Commons ranking third or fourth after the Chief Whip and the Deputy Chief Whip.
 He or she is the Deputy to the Lord Chamberlain of the Household.
 The Vice-Chamberlain's main roles are to compile a daily private report to the Sovereign on proceedings in the House of Commons and to relay addresses from the Commons to the Sovereign and back.
 As a member of the Royal Household, the Vice-Chamberlain accompanies the Sovereign and Royal Household at certain diplomatic and social events, particularly the annual garden party at Buckingham Palace.
 When the Sovereign goes in procession to Westminster for the State Opening of Parliament, the Vice-Chamberlain stays and is "held captive" at Buckingham Palace.
 This custom began with the Restoration (1660), because of the previous Vice-Chamberlain's role in the beheading of Charles I.
Court appointments are the traditional positions within a royal, ducal, or noble household.
 In the early medieval period, when such households were established, most court officials had either domestic or military duties; the monarch's closest advisers were those who served in the household.
 However, as time went by, most of these positions became hereditary, and their role in the running of the household was gradually eroded.
 In England, for instance, the Lord Great Chamberlain and the Earl Marshal were originally responsible for the running of the royal household and the royal stables respectively; however, from the late medieval period onwards, their roles became largely honorary, their places in the household being taken by the Lord Chamberlain and the Master of the Horse.
The Royal Banner of the Royal Arms of Scotland, also known as the Royal Banner of Scotland, or more commonly the Lion Rampant of Scotland, and historically as the Royal Standard of Scotland, (Scottish Gaelic: "Bratach rìoghail na h-Alba" , Scots: "Ryal banner o Scotland" ) or Banner of the King of Scots, is the Royal Banner of Scotland, and historically, the Royal Standard of the Kingdom of Scotland.
 Used historically by the King of Scots, the banner differs from Scotland's national flag, the Saltire, in that its correct use is restricted by an Act of the Parliament of Scotland to only a few Great Officers of State who officially represent the Sovereign in Scotland.
 It is also used in an official capacity at royal residences in Scotland when the Sovereign is not present.
The Lord Chamberlain or Lord Chamberlain of the Household is the senior officer of the Royal Household of the United Kingdom, supervising the departments which support and provide advice to the Sovereign of the United Kingdom.
The office of the Surveyor of the King's/Queen's Pictures, in the Royal Collection Department of the Royal Household of the Sovereign of the United Kingdom, is responsible for the care and maintenance of the royal collection of pictures owned by the Sovereign in an official capacity – as distinct from those owned privately and displayed at Sandringham House and Balmoral Castle and elsewhere.
 The office has only been full-time since 1972.
 It now operates in a professional capacity with a staff of a dozen people.
The royal coat of arms of the United Kingdom, or the Royal Arms for short, is the official coat of arms of the British monarch, currently Queen Elizabeth II.
 These arms are used by the Queen in her official capacity as monarch of the United Kingdom.
 Variants of the Royal Arms are used by other members of the British royal family; and by the British government in connection with the administration and government of the country.
 In Scotland, there exists a separate version of the Royal Arms, a variant of which is used by the Scotland Office.
 The arms in banner form serve as basis for the monarch's official flag, known as the "Royal Standard".
The office of Surveyor of the King's/Queen's Works of Art in the Royal Collection Department of the Royal Household of the Sovereign of the United Kingdom is responsible for the care and maintenance of the royal collection of works of art owned by the Sovereign in an official capacity – as distinct from those owned privately and displayed at Sandringham House and Balmoral Castle and elsewhere.
The Master of the Revels was the holder of a position within the English, and later the British, royal household, heading the "Revels Office" or "Office of the Revels".
 Originally he was responsible for overseeing royal festivities, known as "revels", and he later also became responsible for stage censorship, until this function was transferred to the Lord Chamberlain in 1624.
 However, Henry Herbert, the deputy Master of the Revels and later the Master, continued to perform the function on behalf of the Lord Chamberlain until the English Civil War in 1642, when stage plays were prohibited.
 The office continued almost until the end of the 18th century, although with rather reduced status.
The Lord Chamberlain's Office is a department within the British Royal Household.
 It is concerned with matters such as protocol, state visits, investitures, garden parties, the State Opening of Parliament, royal weddings and funerals.
 For example, in April 2005 it organised the wedding of Charles, Prince of Wales and Camilla Parker Bowles.
 It is also responsible for authorising use of the Royal Arms.
The Removing Wardrobe was a sub-department of the British Royal Household.
 It was responsible for looking after the furnishings which travelled from palace to palace.
 The office was headed by the Yeoman of the Removing Wardrobe (a sinecure office), assisted by two grooms and three pages, all appointed by the Lord Chamberlain.
 The department was abolished in 1782.
