LONDON — The coffin of Queen Elizabeth II left Buckingham Palace for the last time Wednesday, borne on a horse-drawn carriage and saluted by cannons and the tolling of Big Ben, in a solemn procession through the flag-draped, crowd-lined streets of London to Westminster Hall. There, Britain's longest-serving monarch will lie in state for the world to mourn.
Her son, King Charles III, and his siblings and sons marched behind the coffin, which was topped by a wreath of white roses and her crown resting on a purple velvet pillow.
