European corporates and advisers have said they would like to see the introduction of US-style criteria to assess whether a merger is anti-competitive.

At a forum hosted by Lehman Brothers and law firm Allen & Overy in London, around 90 delegates from corporates, banks, law firms and institutional investors gathered to discuss proposed changes to European Commission merger control. Stephan Ryan, Anna Papaioannou and Daniel Dittert, three European Commission Merger Taskforce officials, were also present.
