In page Lord Mayor of London:

"

The importance of the office is reflected in the composition of the Accession Council, a body which proclaims the accession of new sovereigns. The Council includes the Lord Mayor and aldermen of London, as well as members of the House of Lords and privy councillors. At the coronation banquet which follows, the Lord Mayor has the right to assist the royal butler. The same privilege is held by the lord mayor of Oxford, while the mayor of Winchester may assist the royal cook. Such privileges have not been exercised since 1821, when the coronation banquet (celebrating the coronation of George IV) was last held.[citation needed]
