Zamira Hajiyeva, wife of the former head of the Azerbaijani state bank, who was jailed for fraud, has been refused permission to appeal to the Supreme Court against a court order forcing her to reveal where exactly she got so much money.

The UK’s National Crime Agency will be able to seize £22m worth of property if she fails to comply, including her Knightsbridge home and a golf course in Berkshire worth £11m.

Graeme Biggar, director general of the national economic crime centre at the NCA, said: “This is a significant result which is important in establishing unexplained wealth orders as a powerful tool for financial investigations. This was the first UWO secured and the NCA has been determined throughout the many legal challenges faced over the last two years. This case will set a helpful precedent for future UWO cases.

“There are no further routes for Mrs Hajiyeva to appeal against the order. She will now be required to provide the NCA with the information we are seeking in connection with these assets.”
