The King and Queen enjoyed a very sunny day at Royal Ascot on Friday as they attended day four of the esteemed racing festival on Friday.
Charles, 77, and Camilla, 78, led the way in the front carriage of the traditional procession as they marked their fourth day in a row at the racecourse.
Wearing a suit despite soaring temperatures and highs of 28C, the King appeared in bright spirits as he waved from the carriage while the National Anthem played.
The outing comes as it was revealed that Prince Harry is set to bring his wife, Meghan Markle, and their two children, Prince Archie, seven, and Princess Lilibet, five, to the UK next month for his Invictus Games events.
It's currently unclear what their security arrangements will be, though The Sun has reported that King Charles has offered to help cover the family's first joint trip to the UK in four years. This has not been officially confirmed, however.
See below for the best pictures for day four of Ascot – and all the royals that attended.

The King and Queen are both huge fans of horse racing, having also attended the Epsom Derby earlier this month.
On Tuesday, they were left disappointed, however, as their horse failed to win its race.

Today, however, their Majesties appeared in great spirits after watching the first race from the Royal Box.
