Prince William vows to ban Sarah Ferguson from the royal family

William, 43, who lives in Windsor with Catherine, Princess of Wales, 44, and their three children, is believed to have influenced previous decisions about Andrew’s place of residence.

King Charles, 77, formally revoked Andrew’s military titles and royal patronages last year, but aides have long suggested William supports an even firmer approach.

A palace source said: ‘William’s approach has hardened considerably in recent years, especially when it comes to the public status of the monarchy. He is well aware that trust in the institution is fragile and that any further controversy could have long-term consequences. According to him, there is simply no room for error anymore.’

‘He sees the reputational risk in very stark terms – either you protect the crown at all costs, or you allow more and more damage to be done. From his position, a clear separation is the safest and most responsible option. According to him, setting firm boundaries and maintaining a visible distance is the only realistic way to protect the monarchy against further consequences.’

On Thursday, February 19, Andrew was arrested on suspicion of misconduct in public office due to his connections to the vile pedophile.

He was released hours after a police raid.
