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.

Freshfields Bruckhaus Deringer litigation partners Ian Terry and Matthew Bruce had been acting for Anisimov, with 3 Verulam Buildings' Ali Malek QC and Sonia Tolaney QC instructed as counsel.

Welcoming the decision, Bruce said: "Mr Berezovsky has discontinued the claims against Mr Anisimov in their entirety; claims which Mr Anisimov has consistently denied."

Berezovsky's action against Salford, which related to mismanagement, had seen Macfarlanes litigation partner Iain Mackie representing Salford alongside Brick Court Chambers' Alan Maclean QC. Details of the settlement in the case are confidential, with Russian broadcaster RT reporting that Salford's legal costs are as much as $5m (£3.1m).

Both cases were scheduled to be heard in November.

The terminations follow the conclusion of the high-profile $6bn (£3.8bn) battle between Berezovsky and Chelsea FC owner Abramovich, which culminated last month in a conclusive loss for Berezovsky.

Berezovsky was described by Mrs Justice Gloster as "an unimpressive, and inherently unreliable, witness, who regarded truth as a transitory, flexible concept."

Following the judgment, Berezovsky also ended his $3bn (£1.9bn) claim against the Patarkatsishvili family on 13 September, with Signature Litigation founding partner Graham Huntley advising the family of now-deceased Georgian billionaire Arkady 'Badri' Patarkatsishvili and Addleshaw Goddard litigation partners Mark Hastings and John Kelleher representing Berezovsky.

The news comes after the termination of the $1bn (£616m) dispute between Russian oligarch Oleg Deripaska and rival billionaire Michael Cherney over a 20% stake in aluminium giant Rusal last week.

Quinn Emanuel Urquhart & Sullivan partner Sue Prevezer QC had been acting for Deripaska, with Blackstone Chambers' Thomas Beazley QC and One Essex Court's Alain Choo Choy QC instructed as counsel.

Dechert litigation partner Andrew Hearn was advising Cherney , alongside Mark Howard QC from Brick Court Chambers and Essex Court's David Foxton QC.

The dispute, which dates back to 2008, centred around a claim by Israeli-based businessman Cherney that Deripaska had reneged on a deal to pay him for a 20% stake in Rusal that he had handed to Rusal chief exec Deripaska to be held in trust in London in 2001.

In a statement, Dechert said: "Mr. Cherney announces that his litigation in London against Mr. Deripaska has been terminated. Neither party will be making any further comment in relation to the litigation or matters raised therein."
