Manchester United manager Jose Mourinho has been accused of using a trust fund located in New Zealand in the name of his wife to avoid paying tax.
European publications first accused Mourinho of moving millions of pounds offshore, including to a trust names Kaitaia Trust located in Auckland, to minimise his tax bill on December 3.
Mourinho has strongly denied any wrongdoing.
The investigation dubbed Football Leaks is based on millions of leaked documents and was conducted by the European Investigative Collaborations consortium. It claims to have found evidence suggesting that tax officials in Britain and Spain had been misled by Mourinho's advisers when he was manager of Real Madrid in Spain from 2010 to 2013. Top football players Cristiano Ronaldo and Mesut Ozil were also named in the documents.
During Mourinho's Real Madrid period he did not originally pay tax on his image rights earnings to the Spanish tax authorities.
