As far as the eye can see, there are people on Windsor’s The Long Walk, says journalist Becky Cotterill.
Screens have also been established so mourners can watch the state funeral take place.
Just after 3 pm this afternoon, The State Hearse will travel up The Long Walk to St George’s Chapel for the committal service.
There will be a procession led by a dismounted attachment of the Household Cavalry, with pipers and drums and a band from the Coldstream Guards. Members of the Queen’s personal staff will follow.
The route will be lined by members of the Armed Forces.
