The Prince and Princess of Wales have released an emotionally charged video ahead of their appearance at this year's Trooping the Colour parade.

The footage, released on their official social media pages, showed a tender moment between Princess Kate and her daughter Princess Charlotte. Watch the video below…

Ever the doting mother, the Princess was seen gently stroking Charlotte's hair and pulling it over her dress as they waited for their carriage ahead of the parade.

"All set for The King's Birthday," the caption read. The day marks Princess Kate's triumphant return to public life in the midst of her cancer treatment as she joined the royal family to celebrate the King's official birthday.

After spending much of the year coming to terms with the diagnosis and receiving ongoing chemotherapy, the future queen looked relaxed as she travelled with her family in the glass state coach.

She was surrounded by other members of the family, with her husband the Prince of Wales, Colonel of the Welsh Guards, on horseback, as were the Princess Royal, Colonel Blues and Royals, and the Duke of Edinburgh, Colonel Scots Guards.

The Princess of Wales could be seen smiling and chatting with her children in the carriage before they arrived at Horse Guards Parade in Whitehall. In a change from last year, Princess Kate watched Trooping the Colour from a balcony with her children.
