Allen & Overy's mission is to blend local roots with international expertise. Its Middle East network boasts offices in Dubai, Abu Dhabi, Doha and Riyadh, where it recently formed an exclusive alliance with local practice Zeyad S Khoshaim Law Firm. 

Last year, the firm added an Istanbul office to its network of 42 offices in 29 countries. 

"A sophisticated operation and a very strong player with on-the-ground expertise in the region," is how the judging panel described 2013′s International Law Firm of the Year. 

The firm has an enviable regional client base, which includes The Abraaj Group, Mubadala, Gulf Investment Corporation, NBAD, Orascom and Dubai World. 

Recent panel wins include Qatari Diar Real Estate Investment Company (Qatari Diar), HSBC Middle East and Etihad Rail. 

Over the last year, the firm has advised on an impressive roster of headline deals. In the corporate field, headline deals included the US$9bn (£5.9bn) deal to relocate OCI, Egypt's largest listed company, to Amsterdam. In Abu Dhabi, the corporate team combined with colleagues in the property department to advise Aldar Properties on its US$3bn (£2bn) merger with Sorouh Real Estate. The deal was the first public company merger implemented under the universal succession provisions of the Companies Law. 

Meanwhile, the firm's Islamic finance and capital markets teams have been working on several eye-catching sukuk deals. These include acting for HSBC on the General Authority of Civil Aviation sukuk – the largest-ever sukuk in Saudi Arabia and the first Saudi sovereign sukuk.
