Reckitt Benckiser is on the hunt for a new general counsel after the surprise departure of legal chief Christopher Roberts.

Roberts left the Anglo-Dutch consumer goods giant in September and it is understood that he is yet to take on another position.

Reckitt's chief financial officer, Colin Day, has temporarily taken charge of the company's 25-strong legal team as no replacement has yet been appointed. The company is continuing to recruit, however, with a search currently running for a legal director to report to Roberts' successor.

Roberts joined the company in October 2004 from US tech outfit Sybase, where he had held the position of European general counsel since 1999. He replaced general counsel John Guidry, who quit after just one year in the post.

Roberts sat alongside National Grid legal chief Helen Mahy, Barclays general counsel Mark Harding and Reuters general counsel Rosemary Martin on the executive committee of FTSE 100 in-house lobbying group, the GC100.

Advisers to Reckett include Simmons & Simmons and Freshfields Bruckhaus Deringer and primary corporate adviser Slaughter and May.

Freshfields corporate partner Mark Rawlinson led the team advising the household goods company on its £19bn bid for Boots Healthcare International in 2005 after Slaughters was conflicted by acting for Boots.

Reckitt, which counts numerous household consumer products among its brands, has operations in 60 countries and annual revenues of almost £5bn. The company declined to comment on the departure.
