Thousands, if not millions, of people are expected to see the Queen lying in state from this Wednesday (September 14).
Westminster Hall will be open 24 hours a day for four days for crowds to view the Queen's coffin. However, officials are warning of huge queues that could last hours.
Official government guidance states: "If you wish to attend the Lying-in-State, please note there will be a queue, which is expected to be very long. You will need to stand for many hours, possibly overnight, with very little opportunity to sit down as the queue will be continuously moving."
