Several more Am Law 100 and leading international firms have landed roles advising various parties in connection with the collapse of commodities and derivatives broker MF Global Holdings, which sought Chapter 11 protection in New York on Monday as a result of its exposure to Europe’s mounting sovereign debt problems.

Weil, Gotshal & Manges and British firm Ashurst are advising on the U.K. administration of MF Global UK and MF Global UK Services, according to U.K. publication Legal Week. The MF Global administration marks the first time since Lehman Brothers collapsed in September 2008 that the U.K.’s new proceedings for winding down financial services firms have been tested.
