The Duke and Duchess of Cambridge sent a clear message to the public by taking Prince George and Princess Charlotte on a surprise Jubilee visit, a royal expert has said.
The two youngsters carried out their first-ever official engagement when they joined their parents on a trip to Cardiff Castle on Saturday.
It was unknown that they were to accompany their parents and when there they met performers and those staging a special Jubilee concert, which was taking place in the castle grounds.
