No your eyes do not deceive you, that is royalty mucking it on the Tube with regular plebs.
The royal pair got papped by passengers and the press as they took a three minute trip on the London Underground to mark the 150th anniversary of the transport network. The last time Charles was on public transport was 27 years ago when he opened Terminal 4 at Heathrow, so things had changed for the prince. Apparently himself and Camilla got specially designed Oyster cards for their trip, even though they were only on board for 180 seconds. Best part? Charles and Camilla overly amused by Platform 9 3/4. You may be royal but you're still Muggles lads.
