LONDON — Departing Buckingham Palace for the last time, Queen Elizabeth II was escorted by a grand royal procession carrying her coffin atop a gun carriage and past London’s landmarks to the historic hall where she will lie in state until her funeral next week.

Her son Charles, the new king, walked behind the coffin along with his siblings, while Princes William and Harry walked side by side.

Cloaked by the Royal Standard and adorned by her crown, the queen's coffin was flanked by uniformed soldiers along a ceremonial route lined by flags and vast crowds in the British capital, with Big Ben tolling and guns firing each minute.

Hundreds of thousands of mourners from across the country will then have their final chance to file past at Westminster Hall and say goodbye to Britain’s longest-reigning monarch
