Prince William told schoolchildren his favourite colour and his "best guard" on a visit to the Isles of Scilly. After arriving on a pilot boat and meeting local business, a pupil asked him, "is the King's son allowed to have lunch with us?", to which the Prince of Wales replied, "Yes, is that okay? I'd love to do that". Report by Brooksl. Like us on Facebook at http://www.facebook.com/itn and follow us on Twitter at http://twitter.com/itn
