Back in April 2019, royal expert and Vanity Fair correspondent Katie Nicholl told Fox News she believed Harry, 35, was the mastermind behind the couple’s move from Kensington Palace to Frogmore Cottage, a house on the grounds of Windsor Estate.

The move also meant that the brothers would no longer be living in close proximity to each other.
