“The Duke of York will continue not to undertake any public duties and is defending this case as a private citizen.”
However, according to Nicholas Witchell, a royal correspondent for the BBC, the Prince of Wales and his son, the Duke of Cambridge had a hand in advising the Queen to strip his privileges.
Speaking on BBC News at Ten, he said: “I think we can detect the hands of Charles and William in all of this.
“It would be very odd if the Queen was not consulting them – was not taking their council – particularly in the absence of the Duke of Edinburgh.
“They will be concerned, I’m sure, for Andrew at a human level, but they are very much more concerned for the reputation of the institution.
“Andrew’s position regarding the regiments was plainly untenable, he has agreed, we’re told, not to use the styling of HRH anymore and he will fight this case as a private citizen.”
The comments come as Prince Andrew faces a court showdown after a New York judge ruled Virginia Guiffre’s lawsuit against him could go ahead.
Ms Guiffre has alleged the duke sexually assaulted her when she was a teenager.
