It might have been Her Majesty's birthday but duty called for the Queen as she joined the King at the State Opening of Parliament.
It is the monarch's duty as head of state to formally open each new session of Parliament amid tradition and customs dating back centuries.
It comes just 12 days after Charles appointed new prime minister Keir Starmer at Buckingham Palace following Labour's victory in the general election.
After travelling from Buckingham Palace in the Diamond Jubilee State Coach, Charles and Camilla put on their robes of state as they entered the Palace of Westminster.
The King wore the Imperial State Crown, which contains 2,868 diamonds, 17 sapphires, 11 emeralds, five rubies and more than 270 pearls and weighs more than a kilogramme.
Meanwhile, the Queen sported the George IV Diadem, which dates back to 1820 and contains 1,333 diamonds and 169 pearls.
The King opened Parliament and delivered his speech from the throne in the Lords' Chamber, with his words written by the newly elected Government – the first Labour one of his reign – setting out their agenda for Parliament's new session.
Charles said the Government's programme will be "based upon the principles of security, fairness and opportunity for all" with the announcements of draft laws on nationalising the railways and to speed up the delivery of "high-quality infrastructure and housing".
The State Opening comes after Charles and Camilla visited the Channel Islands for an official trip, with the Queen seen sporting a bandage in Guernsey on Tuesday as she nursed a sprained ankle.
The royal family shared a beautiful photograph of the Queen on Instagram Stories, showing her wearing a green leaf print dress as she greeted the crowds at the Sandringham Flower Show in 2023.
And the Prince and Princess of Wales chose an image of Camilla, taken by Kate and used for a special royal edition of Country Life in 2023, for their birthday message.

Their Majesties travelled from Buckingham Palace in the Diamond Jubilee State Coach.
The black carriage with gilded decorations is the newest in the Royal Mews.
It has shock absorbers to stop it from swaying, and heating, internal lights and power windows.
It was first used by the Queen at the state opening of Parliament in 2014.
The carriage is more than five metres long, weighs over three tonnes and needs six horses to pull it.
Built in Australia, it combines traditional craftsmanship and modern technology, and its aluminium body is prevented from swaying by six hydraulic stabilisers.

Charles added that the NHS will be improved to be a "service for all".
There are also plans for reforms on the rental sector and a smoking age ban to be introduced.

The new prime minister and Labour leader, Sir Keir Starmer, and former PM Rishi Sunak were seen chatting ahead of the ceremony.
Starmer led Labour to a landslide victory at the 2024 General Election, ending 14 years of Conservative government with Labour becoming the largest party in House of Commons.
