CMS Cameron McKenna has become the latest law firm to pick up an advisory role relating to the €136m (£120m) negligence claim against Linklaters by Credit Suisse.

The City firm has been instructed to advise Italian independent Gianni Origoni Grippo & Partners, which faces a counter-claim by Linklaters stemming from advice the two firms gave on a bond deal with Italian food company Parmalat in 2001.
