It’s no secret that Britain’s democratic procedures are a little arcane – and that's no clearer than today, the state opening of parliament.
As its centrepiece, King Charles will deliver his first King's Speech since becoming monarch, though he also stood in for the Queen in 2022.
But there's a lot more pomp and ceremony than that – notably the presence of Black Rod.
No, that's not a villain from some sort of comic book film, but the King's representative in Parliament.
Black Rod traditionally marches up to the doors of the Commons, and they are slammed in her face. Then, they are reopened for her to solemnly trot down the hall and introduce the King's speech.
It's all a bit weird, isn’t it? However, there is some method to the madness, so we’ve unravelled it.
Black Rod enters the Commons to request MPs walk across the building to enter the House of Lords for the Queen\u2019s Speech, a key tradition in the state opening of Parliament http://bloom.bg/3srLLZ0\u00a0pic.twitter.com/8XfYvfjhD3
Black Rod is the Chief Lady Usher to the Sovereign and an officer of the Order of the Garter, a role spanning parliament and the Royal household that dates back to 1348.
There are thought to have been 60 holders of the position since then.
The title “Black Rod” comes from the staff carried by the holder - it is made of ebony and is topped with a golden lion.
The position of Black Rod also exists in Commonwealth countries Canada, Australia and New Zealand.
What does it involve?
Black Rod summons MPs to hear the Queen’s Speech. Traditionally the door of the Commons is slammed in Black Rod’s face to symbolise the Commons’ independence, even though it comes across as pretty aggressive.
Rod then knocks on the door three times, and everyone acts surprised to see them walk back in.
As well as cutting about at ceremonial events, Black Rod manages a team of 30 staff involved in the day-to-day running of the House of Lords and makes a cool £93,000 for doing so.
The @HouseofCommons will meet at 11:25am for the State Opening of Parliament and the #KingsSpeech. Once the King is seated in the House of Lords, Black Rod will summon MPs from the Commons Chamber.\n\nAs tradition dictates the door of the Chamber is closed as Black Rod approaches.
OK, but who is Black Rod?
Since 2017, Sarah Clarke has held the role and is the first woman to do so in its 650 year history. Prior to this, she was in charge of admin at Wimbledon and has also worked for the Olympics and the London Marathon.
How have people reacted to Black Rod?
Unsurprisingly, a tradition so bizarre has bemused people on social media today.
Here is a snippet of the reaction:
As with nervous excitement we await the echoey footsteps of Black Rod, it is beholden on us once again to revisit this now deleted \u2014 but never forgotten \u2014 piece of gold
Is today Black Rod prancing about day?
Any other political nerds going to miss Skinner's Black Rod entrance quip today?
Not yet Black Rod! Be patient. \n\n\ud83d\ude44Every year... \n\n@LindsayHoyle_MP
