Following the email being brought to light, the Palace launched an inquiry into the claims.
The Daily Mail understands the Palace spokesperson has said they are very concerned and taking this seriously by including “Members of staff involved at the time, including those who have left the household, will be invited to participate to see if lessons can be learned.”
A source close to the inquiry reportedly told The Mirror “The Palace is taking each and every allegation very seriously and wants to get to the truth of the matter.”
“But Meghan is adamant the staff were not up to their job and could not deal with the pressure of working for her.
“The Duchess is preparing to fight back against what she has termed ‘a smear campaign'”
Meghan wants a point-by-point breakdown of all the claims, as a senior Palace source in March confirmed her office had ‘written to request’ all documents, emails or text messages.
The Daily Mail understands the source now fears there will be a “brutal showdown.”
A spokesperson for the Dutchess said she “is saddened by this latest attack on her character.”
The inquiry into the claims is being conducted by an independent legal firm hired by the Palace and is ongoing.
