With over 20 years’ experience at the forefront of sanctions and international law, I advise on all aspects of sanctions regimes, export controls, and international trade law. I also bring decades of expertise in reputation management, including media law, defamation, copyright, intellectual property, and data protection.

I was the strategic lead in landmark sanctions cases before the European Court of Justice, including Sheikh Yassin Kadi v Council of the EU — known globally as Kadi 1 and Kadi 2. Both were heard before the Grand Chamber of the European Court of Justice, the highest court in Europe, where the court sharply criticised the absence of due process and rule of law protection in the application of sanctions. 

Working with trusted legal advisers in the US and EU, I have secured the worldwide delisting of many clients. These cases have helped shape new legal protocols for challenging international sanctions across multiple jurisdictions.

I have experience of UN sanctions, and of advising businesses and investors on compliance with economic sanctions around the world.

My clients include ultra-high-net-worth individuals, philanthropists, royalty, rulers of states and their families, religious leaders, and internationally recognised figures in the arts and media.
