Devereux Chambers' Jonathan Fisher QC has been instructed to advise the Treasury Committee on its investigation into the Libor rate-rigging scandal, as details of the inquiry continue to emerge.

Fisher, who specialises in cases involving corporate and financial crime, was appointed to advise Parliament on the inquiry earlier this month.

Fisher said: "I have done work for the government before, but this is my first parliamentary advisory role of this kind. I was instructed shortly after a session of interviews on the BBC and Sky when the Barclays scandal broke.

"I am mainly advising on the issues relating to civil and criminal enforcement."

The news follows a number of other advisory appointments at the Bar, with One Essex Court's Jeffery Onions QC and David Wolfson QC and Blackstone Chambers' Brian Kennelly instructed by Hausfeld & Co to act for some of the claimants against Barclays, including large corporates, international banks and municipal authorities.

The news comes as it was confirmed today (24 July) that former Freshfields Bruckhaus Deringer senior partner Anthony Salz will lead an independent inquiry at Barclays into the bank's culture and practices.

Freshfields is advising the Bank of England in relation to the scandal, with dispute resolution partner Ian Taylor leading the team acting for the magic circle firm's institutional client. Other law firms with roles relating to Libor include Sullivan & Cromwell, Clifford Chance, Morrison & Foerster, Norton Rose and Dechert.
