The shock claim was contained in ‘Battle of Brothers’ by Robert Lacey, a royal historian, which will be published later this month. Mr Lacey argued the Duchess of Sussex clashed with her brother-in-law, the future King, over her promotion of “woke” causes.
In an extract published by the Daily Mail he said: “William did not see his future role as monarch – nor his current role as heir – as a matter of him working to maintain the nation’s feelings in harmony while his activist brother and his wife jumped up and down beside him cultivating political and cultural divisions in pursuit of their trendy vision of doing good.
“Windsors do not do ‘woke’.”
The issue came to a head when Meghan guest edited the September 2019 issue of British Vogue.
Meghan chose to put 15 “trailblazing female changemakers” on the front cover alongside the title “forces for change”.
Those featured included controversial political figures like climate change activist Greta Thunberg and Jacinda Ardern, Prime Minister of New Zealand.
Also included were “diversity advocate” Sinéad Burke, “women’s rights advocate” Salma Hayek Pinault and “body positivity activist” Jameela Jamil.
Explaining her work Meghan said: “These last seven months have been a rewarding process, curating and collaborating with Edward Enninful, British Vogue’s editor-in-chief, to take the year’s most-read fashion issue and steer its focus to the values, causes and people making impact in the world today.
“Through this lens I hope you’ll feel the strength of the collective in the diverse selection of women chosen for the cover as well as the team of support I called upon within the issue to help bring this to light.

The couple dated for just a year and a half before becoming engaged.
Mr Lacey quotes Prince William as asking his brother “Are you sure?
“This all seems to be moving rather quickly.”
Harry and Meghan met on a blind date in London early in June 2016.
They announced their engagement in November 2017 and the wedding took place the following May.
Mr Lacey wrote: “William couldn’t understand how Harry could contemplate marrying this still unknown and untested quantity less than two years after their first meeting.”
William was reportedly also concerned Harry and Meghan refused to name the godparents of their son, Archie Mountbatten-Windsor, after he was born in May 2019.
Mr Lacey said: “‘Friends’ of William suggested that the future king, only five places clear of Archie in the order of succession, could not comprehend how such a basic matter of constitutional principle had been misunderstood.
“How could any new Windsor royal be christened in a meaningful sense without the newcomer’s sponsors being known, if not present?”
Harry and Meghan announced their bombshell plan to step down as senior members of the Royal Family in January 2020.
