The Palace needs to try harder to reflect modern day Britain but if this is accurate then it’s a shame.
So according to that page 6 piece, not only was there at least one person of colour in a senior role in the RF, but that person, an extremely experienced man of colour in a highly trusted position in the royal household, was denied a role because of his race - denied by MM.
And, if Tina Brown is to be believed, an extremely, extremely experienced elderly white woman was denied a role, based on her age and skin colour, as having nothing to tell MM about palace life. So racist and ageist on the part of MM. And, conversely, implies that MM was unable to learn from a white woman for some reason. As if she's not very bright - extremely insulting to her, as she is mixed race and has married a white man; and even if she wasn't, it implies black people can't learn from white people about things wholly unconnected with skin colour, which is patronising, infantilising and racist.
