Billionaire football club owner Roman Abramovich has been forced to deny allegations of money laundering and contact with criminal organisations.

The Russian oligarch, who was refused a visa renewal by the UK Home Office to live in England, wanted to set up home near the exclusive Swiss ski resort of Verbier in Canton Valais.

But the Federal Office of Police (Fedpol) advised immigration officials to reject his application.

Journalists from Tamedia, Switzerland’s largest media group, obtained this secret Fedpol file and fought for the right to publish the damning verdict on Abramovich.

Investigative journalist Thomas Knellwolf said: “After half a year in court we can reveal that Swiss federal police see Chelsea Football Club boss Roman Abramovich as a possible danger for the country. That's why he can't move to Switzerland.”

Abramovich vehemently denies the allegations.

His lawyer Daniel Glasl said: “We are extremely disappointed by the release and publication of confidential information from Swiss government files regarding Mr Abramovich, which occurred in clear violation of Swiss criminal law and Swiss data protection laws.

“We have filed a request for correction of facts to the Swiss Federal Police and will be filing a criminal complaint against unknown persons responsible for dissemination of this confidential information.
