Mr Goldsmith – who is the brother of minister Zac – made a number of allegations in a series of messages online in response to claims the Duchess was a victim of racism.
One of the three was deleted quickly but the claim Meghan had been unkind is still visible.
Mr Goldsmith – who was a non-executive board member of the Department for Environment, Food and Rural Affairs – said: ‘We are far from perfect, but poll after poll shows British people to be among the most welcoming and the least racist anywhere.
‘At the start Meghan was adored. Crowds thronged the streets at the wedding. Meghan is disliked because she is a manipulative bully who got found out.

The messages were set this morning and one was deleted, although two others still remain, n response to claims the Duchess has been a victim of racism
‘Meghan has come to personify the arrival of America’s deranged culture wars in Britain. ‘
The Duchess of Sussex has been dogged by allegations of bullying, but has always strenuously denied them.
In June Buckingham Palace said it ‘revised’ its HR policies in the wake of a report into allegations of bullying by Meghan.
But it added it would never publish the investigation, with a source claiming at the time: ‘The household seems to be terrified of upsetting or provoking Harry and Meghan.’
Allegations emerged 18 months ago following complaints by staff during a ‘toxic period’ before the couple emigrated in early 2020.
How the 2021 allegations unfolded with a statement from the Duchess of Sussex at the time saying it was a ‘calculated smear campaign’. Harry and Meghan were reportedly not interviewed as part of the probe
‘Broken’ royal aides told of feeling humiliated, ‘sick’, ‘terrified’, left ‘shaking’ with fear, and being reduced to tears.
Meghan was accused of having inflicted ’emotional cruelty’ on her staff and ‘drove them out’. One branded the Sussexes ‘outrageous bullies’.
Lawyers for the Sussexes vehemently denied the couple bullied or mistreated staff allegedly between late 2018 and early 2020.
Meghan then accused the of ‘perpetuating falsehoods’ about her and Harry in their interview with Oprah Winfrey that was released hours after the allegations emerged in March 2021.
Royal aides announced in March last year that they were launching an inquiry into claims that Meghan’s ‘belittling’ behaviour while a working member of the Royal Family drove two female personal assistants out of the household and ‘undermined the confidence’ of a third.
Staff were said to have been left in tears and feeling ‘traumatised’ – with some likening their condition to having post-traumatic stress.
The Royal Household employed a third-party law firm, paid for by the family privately, to probe the claims in a move that some predicted could increase tensions between Harry and Meghan and ‘the institution’.
The allegations have always been strongly denied by the duchess, whose lawyers described them at the time as a ‘calculated smear campaign’. They did not respond to requests for comment yesterday.
Last year a palace spokesman made clear that the specifics of the allegations – which were brought to the attention of senior household staff at the time by Harry and Meghan’s concerned press secretary, Jason Knauf – would not be probed.
MailOnline contacted spokespeople for Meghan but had not received a response at the time of publication.
