King Charles III and Prince William have made a surprise appearance in London today, greeting mourners waiting in the queue to pass the Queen's coffin as she lies in state at Westminster Hall.
The King and the Prince of Wales, as William is now known, were met with cheers and applause as they emerged at Lambeth to say hello to the thousands of people who are lining the capital's south bank to pass the royal casket.
PA reports that many took photographs and pressed against the metal barriers, eager to exchange a word with the King and the heir to the throne as they shook hands with those closest. Several also shouted "God Save the King" and "God Save the Prince of Wales" as each passed by.
BBC News reports that the King spoke to a number of those who have joined the day-long queue, telling one woman: "I hope you're not too frozen."
As the King made his way along the queue people were consistently urged by a security guard to put their "phones down, shake hands and enjoy the moment".
Hundreds of passers-by have lined the pavements in Lambeth, towards Westminster Bridge, to watch the King and the Prince of Wales greeting mourners in the queue.
In line for the Queen's lying in state, one lady offered Charles condolences as he shook her hand, and another shouted: "I can't believe this."
Dozens shouted "hip hip hooray" as Charles and William moved down the line, stopping for a few moments with each person.
Several people called their friends and relatives on the phone to tell them what they had just witnessed.
The Prince of Wales thanked people for waiting in line for many hours for the Queen's lying in state, as he shook hands with mourners.
Several people cried after meeting him, and one woman told him: "You'll be a brilliant king one day".
Charles left before William, both of them in cars surrounded by police vehicles.
The Queue, as it has become simply known on social media, has been as much as a day long as thousands flock to pay their final respects to Queen Elizabeth II following her death at the age of 96.
Politicians and celebrities are among those who have braved the dropping temperatures to say their final farewells to Her Majesty, including David Beckham - who declined an offer to skip to the front.
BBC Weather even included The Queue as a location on a forecast tweet made earlier on Saturday.
