Carole and Michael Middleton have appeared in an extremely rare video taken at the Prince and Princess of Wales' family home, Anmer Hall, in Norfolk.
The Princess of Wales's mother and father were seen alongside Prince George, Princess Charlotte and Prince Louis in the clip, filmed last month while the family were taking their summer break at the royal residence.
The video sees Kate announce to the nation that she has completed her course of preventative chemotherapy treatment.

Kate's mother and father have no doubt been an enormous support network while undergoing her treatment. Spending time with the whole family is something the Waleses embrace, as outlined in Kate's statement.
The Princess of Wales highlighted how the "complex" journey with cancer had made her and Prince William reflect on the simple yet important things in life.

Kate began her course of preventative chemotherapy in late February after tests following unrelated abdominal surgery found that cancer was present.
She added in her statement: "Doing what I can to stay cancer-free is now my focus. Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes."
The mother-of-three continued: "Despite all that has gone before, I enter this new phase of recovery with a renewed sense of hope and appreciation of life.

"Everyone's kindness, empathy and compassion have been truly humbling. To all those who are continuing their own cancer journey – I remain with you, side by side, hand in hand.
"Out of darkness, can come light, so let that light shine bright."
