Bank of America (BoA) has filed a motion to disqualify US law firm Quinn Emanuel Urquhart & Sullivan from representing AIG in a $10bn (£6.3bn) securities litigation case, reports The Am Law Litigation Daily.

The bank argues that Quinn Emanuel is conflicted because Marc Becker, a London partner the firm recruited in 2009, had previously represented Merrill Lynch and a subsidiary as a partner at Munger Tolles & Olson, BoA’s lawyers.
