Prince William and Kate Middleton will back King Charles' Frogmore House eviction of Prince Harry and Meghan Markle.
The Duke and Duchess of Sussex have been asked to vacate their Frogmore Cottage residence.
King Charles and Prince William had previously discussed the decision to request eviction.
The Royals do not want Harry and Meghan to be their neighbors.
Frogmore Cottage is expected to be assigned to Prince Andrew, who will be relocated from Royal Lodge in Windsor Park.
According to Christopher Andersen, author of 'The King: The Life of Charles III,' Queen Elizabeth II indulged Prince Andrew's every extravagant whim.
By cutting costs, Charles is streamlining the monarchy.
Andrew will not be the only royal family member whose belt will be tightened by the new monarch.
