Chelsea owner Roman Abramovich will discover the result of a big-money court case within the next week.
Boris Berezovsky claims that Abramovich "intimidated" him into selling shares in a Russian oil company at a fraction of their value, as well as breaking a promise made during a deal relating to an aluminium company.
Berezovsky, 66, raised allegations of blackmail, breach of trust and breach of contract, and claimed damages of over £3bn.
Abramovich denies the charges, arguing that Berezovsky didn't contribute any money to the business in question.
High Court judge Mrs Justice Gloster will deliver a ruling in London on Friday.
