Boris Berezovsky has dropped his legal action against Russian metal magnate Vasily Anisimov and agreed a settlement with investment company Salford Capital Partners, as the oligarch ties up his remaining litigation in the wake of his high-profile Roman Abramovich dispute defeat.

Berezovsky’s case against Anisimov involved a $2bn (£1.2bn) claim for breach of fiduciary duty and breach of trust over the Russian oligarch’s interest in iron ore producer Metalloinvest.
