Alexander specialises in all areas of commercial law practised at 7KBW, particularly international arbitration, energy, insurance and reinsurance, shipping and private international law.

He is recommended in the legal directories as a leading junior in the fields of Commercial Litigation, International Arbitration, Insurance and Reinsurance, and Shipping .  The Legal 500 describes him as ‘one of the stars of the Bar,’ and he was nominated as International Arbitration Junior of the Year in the Legal 500 2018 Awards.  

In recent years Alexander has been involved in a number of complex and high profile commercial disputes.  Amongst other things, he acted for a number of insurers in the US$1.2 billion claim brought by SBM in connection with the Yme MOPUstor project, and he is currently acting for the Owners in the B Atlantic dispute, which is listed to be hear by the Supreme Court in 2018.  He has also been involved in insurance and reinsurance disputes (many of them in arbitration) relating to Madoff, large-scale buy-to-let mortgage fraud, the Christchurch II earthquake, the Deepwater Horizon oil spill, pensions mis-selling and parallel lotteries. Alexander is equally comfortable being instructed on his own, or working as part of a large counsel and solicitor team.  He appears in all tiers of the English courts, and has acted in a wide range of arbitrations, including under ICC, UNCITRAL, LCIA, LMAA, GAFTA and RSA terms.
