Allen & Overy (A&O) has secured a new corporate client in Germany thanks to a loose referral relationship with rated Mittelstand multidisciplinary partnership (MDP) Susat & Partner. Susat introduced A&O to Frankfurt-listed chemicals group H&R Wasag, which used A&O on its recent acquisition of BP's Europewide oil refinery business. Both Susat and A&O worked on the deal, which saw A&O cream off the high-end and international work, a crucial strategic aim for Anglo-Saxon firms in Germany. It is thought that H&R Wasag plans further European expansion. Susat retains the client relationship. A&O managing partner Cornelius Fischer-Zernin, who led the deal, commented: "If we have clients who need a mid-sized MDP, we can pass them over to Susat for that work."
