Perhaps W2's message at Christmas is a new persona the strange, unstable, Walter Mitty character is developing...
W2 is really Royalty. The W2 Christmas Day message is aimed at usurping the Queens Xmas Day message, and eventually the throne. In the future the BBC will be broadcasting W2's message to the nation at Xmas. Of course, it will be broadcast from his yacht, moored of the Spanish coast with the aircrew standing-by in case there is a need to fly back for meetings with the P.M. over world events.
You heard it here first...
