King Charles III on Monday led a procession through the centre of the Scottish capital Edinburgh behind the coffin of his late mother, Queen Elizabeth II, as it headed to St Giles' Cathedral.

Walking next to the queen's three other children, Charles followed the coffin for the short distance up the Royal Mile from the Palace of Holyroodhouse, where it had rested overnight.

It came amid the sound of guns fired at one-minute intervals from Edinburgh Castle.
