Queen Elizabeth, who missed a Remembrance Sunday service at the Cenotaph due to a sprained back, has been shown standing and smiling while meeting the UK's most senior uniformed military adviser at Windsor Castle.
The Queen, 95, the world's oldest and longest-reigning monarch, met Nick Carter, chief of the defence staff.
The chief of the defence staff is the professional head of the armed forces and principal military adviser to the defence minister.
Carter is due to step down from the role at the end of November.
It is the first time in nearly a month that the monarch has been pictured carrying out an in person engagement since she hosted a reception for the global investment summit at Windsor on October 19.
She held a face to face audience with Prime Minister Boris Johnson last week but was not pictured doing so.
