Documents falsified to evade tax on Abramovich's wealth, BBC finds

An investigation by the BBC and the Bureau of Investigative Journalism has found that documents were falsified to help Russian oligarch Roman Abramovich evade taxes on his wealth. The backdated paperwork was used to make Abramovich's yachts and mansions disappear from official accounts.

The investigation revealed that Abramovich's advisors, including the multinational professional services network Deloitte, were involved in helping him hide his wealth.
