Prince George and Princess Charlotte were some of the youngest guests at Prince Philip's memorial service, reflecting on the life of their great-grandfather.
They walked into Westminster Abbey with their parents the Duke and Duchess of Cambridge before taking their seats in the row behind the Queen and Prince Charles.
The eight-year-old future king and his six-year-old sister looked slightly nervous when they got out of the car and walked towards the building, however some reassuring words from mum Kate saw Charlotte start smiling.
