The State Opening of Parliament is an event which formally marks the beginning of a session of the Parliament of the United Kingdom. It includes a speech from the throne known as the Queen's Speech (or King's Speech). The State Opening is an elaborate ceremony showcasing British history, culture and contemporary politics to large crowds and television viewers.
It takes place in the House of Lords chamber, usually in May or June, in front of both Houses of Parliament. The monarch, wearing the Imperial State Crown, reads a speech that has been prepared by his or her government outlining its plans for that year. A State Opening may take place at other times of the year if an election is held early due to a vote of no confidence in the government. In 1974, when two general elections were held, there were two State Openings.
Queen Elizabeth II has opened every session of Parliament since her accession, except in 1959 and 1963 when she was pregnant with Prince Andrew and Prince Edward respectively. Those two sessions were opened by Lords Commissioners, headed by the Archbishop of Canterbury (Geoffrey Fisher in 1959 and Michael Ramsey in 1963), empowered by the Queen. The Lord Chancellor (Viscount Kilmuir in 1959 and Lord Dilhorne in 1963) read the Queen's Speech on those occasions.
The State Opening is a lavish ceremony of several parts:
First, the cellars of the Palace of Westminster are searched by the Yeomen of the Guard in order to prevent a modern-day Gunpowder Plot. The Plot of 1605 involved a failed attempt by a group of provincial English Catholics led by Robert Catesby to blow up the Houses of Parliament and kill the Protestant King James I and aristocracy. Since that year, the cellars have been searched, now largely, but not only, for ceremonial purposes.
