He has also advised clients on a range of regulatory investigations conducted by authorities in the UK and US, including the Financial Conduct Authority and the Securities and Exchange Commission, and has worked on various contentious restructurings and anti-trust/competition matters, representing clients in the Competition Appeal Tribunal, High Court and the Court of Appeal.

Additional accolades from Chambers and Partners include “he is an excellent person to have at the tiller of substantial litigation” , “he has superb vision for the big picture strategically and always understands what really matters to his clients”. Alexander demonstrates “high attention to detail, is uncompromising and constantly looking for ways to eke an advantage out of the litigation”. He is “extremely intelligent and has a clear grasp of the many different aspects of the case" and “always manages to keep all the plates spinning, in the most complex of matters and in the most challenging situations, with both grit and unending good humour". In addition, “Alexander is very straightforward to deal with and has the ability to patiently explain complex issues in detail. He does an amazing job of keeping things on the road, and he is unflappable in the face of huge, insurmountable challenges. He is very insightful, articulate and fights hard for his clients".

One of the brightest, most tactically astute London commercial litigation partners. Leaves in the dust most of his counterparts at the top firms."

He is “a creative, commercially-minded professional who commands respect. He is a whip-smart commercial lawyer with very good judgement and fun to work with too. He is tremendously bright, has acute commercial judgement, and is a good choice for clients who want a personal service but with Magic Circle brainpower”.
