Zamira Hajiyeva lives in a £15 million house in KnightsbridgeCredit:Paul Grover The banker’s wife at the centre of a McMafia-style financial investigation has had hundreds of thousands of pounds worth of jewellery seized from an auction house where it was being valued ahead of a sale.Zamira Hajiyeva, 55, is currently the subject of the UK’s first Unexplained Wealth Order (UWO) case, amid allegations that she used stolen money to fund an extraordinarily lavish lifestyle.Her husband is the former chairman of the state-owned International Bank of Azerbaijan, and was sentenced to 15 years in jail in 2016 for defrauding the bank out £2.2bn.Last month it was revealed Mrs Hajiyeva, who lives in Knightsbridge, west London, had spent more than £16 million at the nearby Harrods department store.She has denied that the source of her wealth is illegal and is challenging the UWO in the courts.But earlier this week investigators from the National Crime Agency (NCA), who are looking into her financial background, seized almost 50 items of high value jewellery from Christie’s auction house. Around £400,000 worth of jewellery was seized by the NCA from Christie’s Mrs Hajiyeva, who has lived in the UK for more than a decade, is the first person to be the subject of a UWO, which were introduced in an effort to clamp down on people laundering cash in Britain.As well as spending more than £16 million in the Harrods department store over a ten-year period, Mrs Hajiyeva owns a five-bedroom house worth £15 million and also bought the Mill Ride golf and country club in Ascot for £10.5 million.She is also said to have owned a £35 million private jet and had a wine cellar stocked with some of the world’s most expensive vintages. The National Crime Agency alleges that Mrs Hajiyev used fraudulent funds to purchase her home, which is just a short walk from the famous Harrods department store.It was alleged that she paid a deposit of £4 million for the house in 2009 and had cleared her £7.4 million mortgage in just five years.She had made an unsuccessful application to discharge the UWO, but her lawyers are appealing that judgment.She has denied all the claims and her lawyers have stressed that the UWO is part of an investigative process rather than a criminal procedure and does not involved the finding of any criminal offence. The NCA said it had seized the items because investigators believed that the source of the money that had been used to buy them warranted further examination.Earlier this week a district judge at Westminster Magistrates Court said the NCA could hang onto the items for six months to allow further investigation to take place.The items were seized from Christie’s auction house in London, where they were being valued for Zamira Hajiyeva’s daughter, Leyla Mahmudova.The NCA said Christie’s auction house had co-operated with the investigation and had complied with a formal request for information regarding the listed assets.
