When guests reach the back of the line, they will be given a colored and numbered wristband. The wristband also allows people to leave the queue for a short time to use a toilet or get refreshments and then return to their place in the queue. More than 1,000 police officers, flight attendants and volunteers from the Boy Scouts, Samaritans and St John Ambulance will be on hand to help the public.
What can I expect from the queue?
The four-and-a-half-mile queue route takes in London Bridge, Southwark and Waterloo before finishing in Westminster. The furthest it will go is Southwark Park, although this is subject to change and the Department for Culture, Media and Sport (DCMS) will be letting people know via Twitter where the back of the queue is. Along the way, the British Film Institute (BFI) will have an outdoor screen showing archive footage of the Queen and from her reign.
