Meh, I've never really set much store by this account - they quote their "sources" as if they have friends in the RF, but it just seems to be sourced from chatter on online forums like this one, lipstick alley, ARRSE.
No-one is going to believe that she was forced to have a white baby! She was photographed in so many places, defying Royal rules, defying Royal protocol, it was clear that she wasn't prepared to listen to the Queen or respect what she wanted. She wouldn't even be forced to wear a hat or brush her hair, how are they "forcing" her to have a white baby, FFS!
And hate to point out the blindingly obvious, but why would the RF have let them get married in the first place if they were so racist?
Let us not forget that the Queen was Head of State for many countries, not just the UK. Where the people were black. QEII ( RIP) promised to serve ALL of us, not just the whites, FFS. I think for her 70 years on the throne she proved that her word could be trusted, unlike the cable TV actress who has been caught out in 100's of whoppers from her 72 days as a working Royal.
I think most people will not believe this for a second.
