The Queen has travelled to her private Scottish home of Balmoral for the start of her traditional summer break.
Members of the Royal Family are invited to spend time with her at the Aberdeenshire castle every summer.
Outgoing Prime Minister Boris Johnson is among the guests expected to visit the monarch this summer, according to the BBC.
The Balmoral Estate, in the heart of Royal Deeside, has been a place of sanctuary for the Royal Family since the reign of Queen Victoria.
The Queen previously visited the castle in May for a short break ahead of celebrations for the Platinum Jubilee.
She has been scaling back her public appearances due to some mobility issues.
At the end of her Platinum Jubilee celebrations, she said she was committed to serving the country "to the best of my ability, supported by my family".
