The Serjeant at Arms of the House of Commons is a parliamentary official responsible for order in the House of Commons. The office dates to 1415 and traditionally included responsibility for security. The role is now mainly ceremonial. The House of Lords also had a Serjeant-at-Arms (the title was often distinguished by the use of hyphens), dating also from the 15th century. His duties were merged in 1971 with those of Black Rod. Ugbana Oyet holds the post as of October 2022.
