The first public proclamation of the new sovereign will be read at 11am from the Friary Court balcony at St James’s Palace by the Garter King of Arms.

Proclamations are made across the country.

The military will line the streets and join the procession.

Foreign leaders, European royals and key figures from public life will gather in the abbey, which can hold a congregation of 2000.

A national two minutes’ silence will be held.

The same day, the Queen’s coffin will be taken to St George’s Chapel at Windsor Castle for a televised committal service.

Later, there will be a private interment service with senior royals.
