French firm Darrois Villey Maillot Brochier, Benelux firms De Brauw Blackstone Westbroek and Nauta Dutilh, and US outifts Latham & Watkins and Wachtell Lipton Rosen & Katz have scooped the lead roles on the world’s biggest advertising merger.

The five firms are advising French company Publicis and New York-listed Omnicom on the proposed merger, revealed yesterday, which will create a business with a market capitalisation of around $35bn (£22.7bn) and revenue of nearly $23bn.

The creation of Publicis Omnicom has been approved by both boards and sees the creation of a Dutch holding company with operational head offices in Paris and New York. The company would be listed in New York with a secondary listing on Euronext Paris.
