This is the 'Meghan bullying bombshell' bit:
Some say a report on bullying accusations against Meghan Markle has never been released because it would also raise questions about the behaviour of the Queen’s second son.
The way Andrew treated staff caused one royal aide to describe him as ‘a deeply unpleasant man’. Colin Burgess, who served as equerry to the Queen Mother for many years, felt he was treated with disdain by Andrew, in ‘stark’ contrast to the respect for staff shown by Prince William and Charles, the then Prince of Wales.
Apparently Andrew was 'never disciplined'.
HM QEII was very, very silly not to bring him up (or have him brought up) better. It was a surprising error on her part, to be so indulgent; although of course in the end she did have to ground him and carry out a kind of preventative demotion of him, so goodness knows what material must have finally been presented to her in order for her to act.
