London giants Allen & Overy (A&O) and Linklaters are sharing the spoils of KLM’s high profile takeover by Air France after securing lead roles opposite Dutch leader Nauta Dutilh.

The merger, which was announced on 30 September, will create one of Europe’s largest airlines under the name Air France-KLM, with a stock market valuation of around E19.2bn (£13.4bn).
