An “elected monarch.”
ETA. Tradition, Ceremony, Symbolism
Motioned by the monarch, the Lord Great Chamberlain raises his wand of office to signal to the Gentleman/Lady Usher of the Black Rod (known as Black Rod), who is charged with summoning the House of Commons and has been waiting in the Central Lobby. Black Rod turns and, under the escort of the Door-keeper of the House of Lords and a police inspector, proceeds to the Members’ Lobby of the House of Commons, and reaches the doors of the Commons.
Leading 17th-century parliamentarian John Hampden is one of the Five Members annually commemorated
In 1642, King Charles I stormed into the House of Commons in an unsuccessful attempt to arrest the Five Members, who included the celebrated English patriot and leading parliamentarian John Hampden.[10][11] Since that time, no British monarch has entered the House of Commons when it is sitting.[12]
On Black Rod’s approach, the Doorkeeper of the Commons orders that the doors are slammed shut against them, symbolising the rights of parliament and its independence from the monarch.[12] The Usher of the Black Rod then strikes with the end of their ceremonial staff (the Black Rod) three times on the closed doors of the Commons Chamber, and is then admitted.
