Princess Kate steps out with Prince William and Prince George in first public appearance in over a month

She beamed in the front passenger seat next to the Prince of Wales, who also grinned behind the wheel of their Range Rover Defender.

Kate donned a light brown outfit paired with a pheasant feather hat while William opted for a sophisticated navy suit, in pictures obtained by The Sun.

The couple appeared relaxed as they joined fellow members of the Royal Family for the service.

King Charles and Queen Camilla were also snapped smiling together in their car today.

The monarch sported his traditional Scottish kilt, as Camilla wore a red and green tartan outfit.

Prince Edward was photographed driving Princess Anne's husband, Timothy Lawrence, James, Earl of Wessex and Sophie, Duchess of Edinburgh to the venue.

It comes after the royal announced her cancer diagnosis via a video message in March and has since remained largely out of the public eye amid treatment.

Kate has attended two public events since revealing her health battles.

She stepped out at Trooping the Colour in June and was met with a standing ovation at the Wimbledon men's final the following month.

The Waleses last appeared together in a video earlier this month to celebrate Team GB ahead of the 2024 Olympics closing ceremony.
