In the early hours of Saturday, hundreds of military personnel took part in the first full rehearsal of the procession in Windsor that will bring the coffin of Queen Elizabeth II to her final resting place. With troops lining The Long Walk, a picturesque path leading to Windsor Castle, the drums and brass of the marching bands echoed into the night. On Monday, they will be doing exactly the same, but this time surrounded by thousands of people expected to travel to Windsor for a final farewell to the monarch.
