The Duke and Duchess of Sussex now face paying back £417,000 a year for the next 30 years. The royal couple paid an eye watering £3.8million deposit on the property.

Harry and Meghan’s new home is located on a private road in a luxury and secluded estate in Montecito.
The property is around a two-hour drive from downtown Los Angeles, and almost every house in the multi-million-pound neighbourhood is designed for privacy, with long driveways and large gates.
Neighbours include Orpah, Ellen DeGeneres, Tom Cruise, Jennifer Lopez, Steven Spielberg, Whoopi Goldberg and Kevin Costner who all live close by.
According to reports, the house was initially listed for £12.9million ($16.9million), so the couple were able to secure a nearly £1.5million ($2million) discount on the asking price.
Page Six has described the property as a 9-bedroom, 16-bathroom mansion that sits on a large lot with a rose garden and century-old olive trees included.
Other key features of the home include a library, spa, wet and dry saunas, a gym, game room, arcade, theatre, wine cellar, and a five-car garage.
The luxurious property also features a swimming pool, tennis courts, and a two-bedroom guest house.
The property was also said to include a tea house and a children’s cottage.
Speaking to Page Six about the couple’s decision to buy a home, a source said they moved in last month.
They said: “Harry and Meghan have been quietly living in their own home in Santa Barbara since early July.
“They are not houseguests of Oprah or anyone else, they bought this home themselves. This is where they want to continue their lives after leaving the UK.”
