The question seems pretty simple to me. When the Met's Royalty and Specialist Protection team recieved that letter in 2018 about Meghan's father, did they tell the relevant people in the Royal Household, including the Private Office? And if so, when and what did they do about it?
If they didnt pass it on, why not? And if they did, who was told and what action, if any, was taken?
Meghan says the letter was shared with her and that she was assured the allegations were being investigated. Surely its reasonable to ask what happened to that information afterwards, and whether anyone else in the institution was made aware of it.
I'm not saying the Royal Family all knew, or that anyone should be judged on allegations alone. But the public deserves to know how this was handled, particularly given the years of criticism Meghan faced for distancing herself from her father.
Who knew what, when did they know it, and what did they do about it?
