The procession has now made its way past Buckingham Palace.
The 775-room world famous palace may be the business centre of the British monarchy where garden parties and receptions for world leaders – like the one last night – are hosted.
But it was also the Queen’s main family home for 67 years, from her coronation to the start of the pandemic in 2020.
It was where she became a mother, the birthplace of Charles, and her younger sons, Andrew and Edward.
And it was where she came home to lie in rest for one night last week, before four days lying-in-state.
For her family, who continue their slow, steady walk to Hyde Park Corner, this will be a poignant moment. For the thousands gathered on the pavements, it’s a final goodbye.
