So in a further twist in the tale: Talk TV presenter, JJ Anisiobi (one of Piers Morgan's colleagues) has just said the royal racist is neither of the people named by PM!
He claims to have an impeccable source (someone who works with the Queen and who is friends with Charles) and has spoken with them today. He knows the name of the person. He says after Oprah was aired, all the royals were upset about being implicated, and for two or 3 weeks were talking amongst each other about who it could be. They pinpointed that one person asked a particular question. JJA does not know if the question was asked innocently or in a racist way - but he does know the person asking the question was neither Charles nor Catherine.
JJ is pretty anti royalist and really does not like the PoW, so he's not protecting her or Charles. He thinks OS has made up the second person.
I mean....wtf? I guess the RF may be feeding him a story to get the heat off C&C and discredit OS.
