Probably the most colourful event in the UK's legislative calendar, this takes place in May or June every year, or after a general election, when the King travels to the Houses of Parliament to open the new parliamentary session. During this event, the Lords, Speaker of the House of Commons, and other office holders can be seen dressed in their ceremonial robes, and there is always an elaborate procession when the King makes his way to the Houses of Parliament from Buckingham Palace. This is one of the few occasions where all branches of the British government are gathered in the same place. Many traditions of the State Opening can trace their origins to a more turbulent past, when the relationship between the monarch and Parliament was sometimes antagonistic. In particular, since the English Civil War, the monarch has been banned from entering the House of Commons chamber, and instead must send a representative (the Black Rod) to summon the MPs to the Lords chamber, where he delivers his speech. Another notable tradition is the holding of a Hostage MP in Buckingham Palace, ostensibly to guarantee the safe return of the monarch, who is released once the King has returned to the palace safely after delivering his speech. While attendance at Parliament itself is limited to special guests that have been invited by the Prime Minister, it is broadcast live on the BBC, and you can also view the King's procession from Buckingham Palace to Parliament from the roadside for free.
The State Opening of Parliament is a ceremonial event which formally marks the beginning of each session of the Parliament of the United Kingdom. At its core is the Monarch's "gracious speech from the throne", which is also known as the King's or Queen's Speech, is read by the monarch but written by the government of the day. In the speech the monarch gives notice of forthcoming state visits, before setting out the government's legislative programme for the new parliamentary session. No business of either the House of Lords or the House of Commons can proceed until the Sovereign's speech has been delivered.
more widely known as the Houses of Parliament
On the UNESCO World Heritage List, the Palace of Westminster is the seat of Parliament in the United Kingdom. It's often termed the "Mother of All Parliaments" - an exaggeration, but perhaps only a slight one. The present building largely dates from the 19th century when it was rebuilt following a fire in a splendid example of Victorian neo-Gothic architecture. The House of Commons (elected Members of Parliament or MPs) is located to the north of the building and is decorated with green leather upholstery, and the House of Lords (unelected Lords) is located to the south and decorated with red leather upholstery.
This small tower across the road from the Houses of Parliament is the only part of the original Palace of Westminster still standing. While it is overshadowed in splendour by the surrounding buildings, it's well worth a visit, and has good displays about the early history of Westminster.
The main residence of His Majesty King Charles III, Her Royal Highness Queen Camilla, and latterly of HM Queen Elizabeth II. In the summer, 19 State Rooms are open to the public. Places are strictly limited, and it might not be possible to just turn up and get a ticket for a specific entry time, visitors should book in advance to ensure admission.
