All eight grandchildren of the late British Queen Elizabeth II gathered today at her coffin for a silent vigil, AP reported.

The sons of the new King Charles III, Princes William and Harry, were joined by their six cousins: Zara Tyndall and Peter Phillips - children of Princess Anne, Prince Andrew's daughters - Princesses Beatrice and Eugenie, and Prince Edward's children - Lady Louise Windsor and James, Viscount Severn.

Prince William, now the heir to the throne, stood with his head bowed by the casket at the head, and his brother, Prince Harry, at the other.

The sons of King Charles III, who are military veterans, were in military uniforms.

As the late queen's grandchildren stood vigil, people continued to file past her coffin to pay their last respects in silence.

Prince Harry, who served in Afghanistan as an officer in the British Armed Forces, wore civilian clothes as Elizabeth II's coffin was carried from Buckingham Palace to Westminster Hall on Wednesday as he no longer performs duties as a member of the royal family.

However, King Charles III requested that his two sons wear their military uniforms to the vigil.

Prince Andrew's daughters have paid tribute to their 'beloved grandmother'.

"We, like many, thought you would be here forever. And we all miss you terribly. You were our matriarch, our guide, our loving hand and back that guided us through this world. You taught us so much and we we will cherish these lessons and memories forever," Princesses Beatrice and Eugenie wrote.
