Meghan Markle and Prince Harry were involved in a “monumental row” before a key royal event, author Tom Bower has claimed.
Both Meghan and Harry attended the 2020 Commonwealth Day Service at Westminster Abbey.
Among the other royals to attend the service included the Queen, Prince Charles, Prince William and Kate.
But in his new book titled: “Revenge: Meghan, Harry and the War between the Windsors”, Tom Bower said an argument took place after the pair were told about changes to the procession.

Tom Bower said the incident took place after "Palace officials decided to publicly humiliate" Meghan and Harry HENRY NICHOLLS
Mr Bower said the incident took place after "Palace officials decided to publicly humiliate” the pair.
He added: "Reality hit two days later, on March 9. A monumental argument blew up after Harry was told that he and Meghan could not join the family’s procession through Westminster Abbey for the annual Commonwealth Day Service.
"Although the order of service listed Harry and Meghan walking behind the Queen, Palace officials had revised their decision. Suspicious about the Sussexes they decided to publicly humiliate them.
"Harry was told that having stepped down from royal duties, he and Meghan would sit and wait with the congregation. The prospect of the televised image of their isolation in the Abbey appalled them.
"By then they were keenly aware of Kate and William’s antagonism. William had not offered a brotherly welcome and Kate was outright distant towards her sister-in-law.
"Eventually, to end the dispute, William and Kate agreed they too would wait with Harry and Meghan. As the members of the Royal Family filed into the Abbey, the frayed relationships could not be concealed.
"Kate had blanked the Sussexes and William’s greeting was cold. Harry looked strained. Meghan’s face showed bemusement."
