Despite being removed from his hundreds of charitable patronages and his office being forced out of Buckingham Palace, Prince Andrew has been seen out and about with the 93-year-old monarch. Earlier this month, the mother and sonattended a church servicein Sandringham.

The decision “shows that the royals can move very swiftly and very ruthlessly,” royal historian Robert Lacey tells PEOPLE.

While Prince Andrew will not perform any more public duties as a member of the royal family, not much else will change at this time.

“He remains a member of the royal family,” a royal source said. “As a royal colonel and a war veteran, you can expect to see him at Remembrance Sunday. You can expect to see him on the balcony at Trooping the Colour too.”
