As the celebrations for the Queen's Jubilee approach, Prince William has praised his grandmother.
The celebrations will centre around the first weekend in June which marks 60 years since Princess Elizabeth's coronation, though she took to the throne in February 1952.
Prince William has said: "She's professional, her ability to know how to move around, who to speak to and how to engage with people within a few split seconds of meeting them".
His brother Prince Harry added: "These are the things that at her age she shouldn't be doing, and yet she's carrying on and doing them. Not just in this country but all around the world."
