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.
