The Chair of Sentebale has deleted her Twitter account following a wave of backlash from supporters of Prince Harry and Meghan Markle.
Dr Sophie Chandauka, who has accused Prince Harry of 'harassment', shut down her social media presence due to abuse.
A spokesman for Sentebale said: 'Dr Chandauka deleted her Twitter account due to the proliferation of online bullying'.
One insider who has worked with Sentebale told MailOnline: 'While the pile-on has nothing to do with the Sussexes themselves, it doesn't look good that much of the venom is from their fans'.

Prince Harry is in "total shock" after being accused of "harassment and bullying" by a charity boss, one of his pals has said.
It is the latest development in a dispute between Sentebale chairwoman Sophie Chandauka and the charity's co-founder Harry, who quit as its patron last week amid a boardroom battle.
Alex Rayner, who attended Eton with Harry and went to the North Pole with him in 2012, claimed he spoke to him over the weekend.
He said the Duke of Sussex, 40, is "shocked" by the accusations and "feels as if he has had one of his fingers cut off".

Rayner insisted Harry was "very happy" for him to "speak for him about how he feels".
He told MailOnline: "He is just beyond heartbroken and flabbergasted that the charity he founded as a teenager has been taken hostage by the chair.
"It feels tantamount to a hostile takeover. He is so upset and hurt and wounded about the things that are being said about him.
"I think it's too early to tell whether he will just walk away now or whether he might try and get it back."

It comes after Harry was accused of sending an "unpleasant" and "imperious" message to Ms Chandauka after she failed to publicly quash rumours of a rift with his wife.
During the prize-giving ceremony at a Sentebale fundraising polo match in Miami last April, the Duchess of Sussex appeared to choreograph who stood next to Harry.
And in an awkward moment Ms Chandauka moved from beside the duke to Meghan's side ducking under the trophy.
The Telegraph claimed a member of Harry's team asked Ms Chandauka to issue a statement to quash any rumours about tensions with Meghan but when she refused the duke reportedly contacted her directly.
