This is the moment a Royal Navy sailor collapsed on Whitehall during a rehearsal for King Charles' Coronation.
Hundreds of soldiers from the military, navy and RAF marched through central London before stopping along Whitehall and standing in silence in the early hours of Wednesday.
Many carried a wide range of instruments such as saxophones, trumpets, horns and cymbals but only the drums were played by marching soldiers until they returned down the Mall after 3am.
