Then the moment we landed in the UK, I got a message from my private secretary at the time
Explaining the terminology, Meghan said: 'A private secretary is sort of like a CEO role in the institution.'
Poor poor rich people. Having to explain to the commoners what a private secretary is so they can follow the sob story. 
Any form of racism, any discrimination against a person based on their skin colour is wrong and should have no place in any work place or institution.
However, a woe is me feature on Oprah is not the way to challenge institutional racism. It's populist bullshit and Meghan comes across as super contrived in the clips that have already been shown. But that is miles better than Harry, he just comes across as a naive rich white man child. Whinging that daddy isn't paying for his lifestyle any longer.
Maybe, now that being independent seems a bit like hard work, they want to force daddy's hand by signalling that if he doesn't pay up and give little Archie and his sister some lovely royal titles, they will reveal that it was x, y, or z who said something racist about master Archie.
