Roman Abramovich withdrew a bid for Swiss residency earlier this year after a police report said he was considered a security threat with links to money laundering.
The Russian-Jewish billionaire wanted to establish legal and tax residency in the village of Verbier, where he owns a large ski resort, and personally approached the head of the Swiss federal police to insist it be granted.
But the Swiss daily Tages Anzeiger reported Mr Abramovich’s application dating from July 2016 was in fact on the verge of being refused because of his alleged money laundering and alleged contacts to criminal organisations.
A police report detailing the allegations was leaked in February this year but only made public on Tuesday after Switzerland’s federal Supreme Court overturned an injunction secured by Mr Abramovich’s legal team.
