Mr Turk moved from South Kensington to Mayfair after his estranged wife, Nurhüda Cevahir, left him and moved to Dubai, according to court documents.

A witness statement filed on behalf of Jonathan Tickner, head of fraud and commercial disputes at Peters & Peters – the firm representing Mrs Isbilen – added: “Peters & Peters have been unable to ascertain on what basis Mr Turk has occupied the premises at St James’ Street.

“It is possible that the order might encroach on the rights of the Crown (or those of another property holder) if Mr Turk is not entitled to the use of the property, or has vacated it. I also note that Peters & Peters have not discovered any obvious payment out to the Crown Estate Commissioners from any of the bank statements in the Mandate Disclosure.”

Mr Turk also owns a property in Nazareth, Pennsylvania, that he purchased in July 2019 for $321,000. A relative living there told The Telegraph on Friday that he was in London and only visited from time to time.

The Crown Estate said it could not comment on individual leases.

However, it said that in the event that rent was due and unpaid, it would pursue the necessary steps to recover monies owed, including via legal proceedings if necessary.
