Operation London Bridge is the codename for the plan for what will happen in the days after the death of Queen Elizabeth II.[1][2][3][4]
The plan was originally devised in the 1960s and is updated several
times each year. It involves planning from government departments, the Metropolitan Police Service, the British Armed Forces, the Church of England, media and Royal Parks of London.
Some key decisions relating to the plan were made by the Queen herself,
although some can only be made by her successor after her death.
The phrase "London Bridge is down" will announce the death of the Queen to the Prime Minister of the United Kingdom and key personnel, setting the plan into motion.
