Members of the congregation, wearing black, are taking their seats in Westminster Abbey in preparation for the funeral service for the late monarch that will begin at 11am.
Coaches transporting heads of state and government and others invited to the funeral have been pulling up outside the Abbey, which opened its doors at 8am.
Queen Elizabeth’s lying in state officially ended at 6:30am as the doors of Westminster Hall have closed and the final members of the public filed past her coffin to pay their respects.
Buses are taking police and security staff to various posts around central London.
London on Monday, which is a public holiday in the UK to mark the late monarch’s funeral, has fallen silent and normal life suspended with no rush-hour traffic snarling up the streets around Parliament Square.
Big screens have been set up across the UK, including in Hyde Park in London and Belfast’s City Hall, so people can watch the service while some cathedrals, theatres and cinemas are streaming the event.
Crowds are filling Hyde Park, which will be one of the sites across the UK that have set up big screens to allow people to watch the service, and a festival-style atmosphere is building.
Mourners are gathering on picnic blankets in front of eight big screens around the park, which are streaming footage of the Queen’s life set to classical music.
Coffee stalls and burger bars have been setting up around the London park and serving customers since about 7am.
“We won’t watch the funeral ourselves though,” said one barista, since the screen is not visible from their stall.
Elsewhere, some cathedrals, theatres and cinemas are streaming the event.
