High-flying Prince: London's newest, biggest green space received the Royal seal of approval today as Prince Harry and the Mayor of London Boris Johnson joined local youngsters for a sneak preview of Queen Elizabeth Olympic Park
Big kid at heart: Harry, dressed in a smart suit, wasn't afraid of getting stuck in as he made his way across a wobbly bridge at the Queen Elizabeth Olympic Park
Having a laugh: The prince and Mr Johnson, both wearing navy suits, met outside the Aquatics Centre and began a walk around the park to meet local schoolchildren
