Mayer Brown Rowe & Maw is facing a $245m (£119.5m) lawsuit from a former creditor of Refco, the futures broker on whose 2005 bankruptcy the Chicago-based law firm advised, it emerged yesterday (26 July).

Thomas H Lee Partners (THL) – which acquired a controlling stake in Refco in 2004 – filed a claim in New York alleging that Mayer Brown had failed to inform it of the true state of Refco’s finances.
