Reynolds Porter Chamberlain (RPC) and Freshfields Bruckhaus Deringer are both advising on a €164m (£102m) claim against Barclays, in the latest allegation of wrongdoing at the bank.

The claim has seen investment firm CF Partners accuse Barclays of using information it shared with the bank when it was looking to buy Swedish carbon trading company Tricorona, before subsequently buying the company after CF Partners pulled out of the deal in the wake of the recession.

CF Partners is arguing that the move breached the confidentiality agreement the bank signed when it provided advisory services while the investment firm was considering the acquisition.

RPC is acting for CF Partners with a team led by financial dispute resolution head Tom Hibbert, with Brick Court Chambers' Tim Lord QC and Richard Eschwege and One Essex Court's Orlando Gledhill instructed as counsel.

Freshfields is advising Barclays with a team headed up by London disputes partner Simon Orton, alongside Ewan McQuater QC, David Quest and Sandy Phipps from 3 Verulam Buildings.

The full case is planned to go to trial in May 2013, after the two parties held a case management conference in the High Court in June this year for the judge to decide what documents are expected to be made available from Barclays.

Barclays sold Tricorona back to its management in July this year.

The news comes in the wake of this summer's revelations over Barclays' role in the Libor rate-fixing scandal, which saw Sullivan & Cromwell take the lead role for the bank on its $450m (£290m) settlement over charges that it attempted to manipulate interest rates. Clifford Chance is acting as UK counsel to the bank.

Meanwhile, the bank's former COO Jerry del Missier taking advice from Morrison & Foerster, while Norton Rose is acting for former chief executive Bob Diamond.

Former Freshfields Bruckhaus Deringer senior partner Anthony Salz was subsequently appointed as the head of an independent inquiry launched by Barclays in the wake of the scandal.
