No shooting, no riding, no friends: How can Andrew fill his days?

While the former Duke of York once lived a life full of royal engagements and duties as a UK trade envoy, he is now effectively stuck in his new abode in Sandringham, unable to leave and with few visitors.

Having already been forced to surrender his shooting licence, the equine-loving Andrew was dealt a further humiliation this week when he was instructed by The Firm to stop riding horses around the Norfolk estate.

Andrew has been stripped of royal titles as a result of his past associations with sex offender Jeffrey Epstein and was arrested on his 66th birthday on suspicion of misconduct in public office.

The ex-prince has denied accusations made in Virginia Giuffre’s book that he had sex with her three times and has said a 2022 out-of-court settlement was not an admission of guilt.

What will Andrew do all day?

Andrew left the Royal Lodge mansion in Windsor last month and is looking to move into Marsh Farm in Sandringham, but is currently at the smaller Wood Farm while renovations take place.

He was told this week that riding on a horseback on his Sandringham estate while subject to the probe would give a "bad look” further restricting what he is able to do, now he lives alone and is estranged from his ex-wife, Sarah Ferguson, and his siblings.

The creation of a sense of unofficial imprisonment was added to this week when builders were photographed installing a high wooden fence around the edges of Marsh Farm’s garden.

"It may not be a formal house arrest, but in practical terms, Andrew's movements are now so tightly controlled it may as well be,” a source has told Radar.

"The optics are everything right now. Allowing him to be photographed riding across Sandringham as if life were normal would send the wrong message. The instruction is clear: keep a low profile and stay out of sight."

Engineers have also been seen installing high-speed internet and Sky TV at his new property, suggesting that he will be spending a lot of his time inside staring at a screen.

Andrew is known to enjoy watching golf on TV and is also a fan of tracking planes, perhaps a hobby that is reminiscent of his days as a pilot in the Royal Navy. As well as war films, he also spends hours playing video games, according to NME - with Call of Duty being a favourite.

A source added: “He loves games like Call Of Duty [and] war games with helicopters. He certainly doesn’t play FIFA, he’s got no interest in football.”

"If he doesn't go to jail, Andrew is doomed to while away his retirement watching TV and gaming,” another source added. “The price for that quiet life from King Charles is that he is basically never seen in public again."

In addition to being cut off from his family, and potentially the line of succession, Andrew is no longer living with his ex-wife and visits from their daughters may be less frequent.

While there are also some staff working to ensure Andrew is catered for and has his chores taken care of, it’s unlikely he will strike up much of a bond with Sandringham staff said to be unhappy at being required to work for him and call him Sir.

Nevertheless, a life indoors appears in Andrew's, at least immediate, future, with the garden of Marsh Farm being his only contact with the outside world.

Another insider told AOL: "He is under no illusion about the level of attention he is facing.

“He knows that a single photograph or casual sighting could reignite controversy. For the moment, he accepts that keeping out of view is the only viable option, even if it deepens the feeling of isolation."
