Alastair has a litigation focussed practice both in the High Court (predominantly the Chancery Division and Commercial Court) and internationally, with particular expertise in banking and finance, financial services, energy and natural resources, company disputes and insolvency. Much of Alastair’s practice has an international flavour, and he is therefore experienced in dealing with issues of foreign law and working with foreign clients, lawyers and experts. Prior to being called to the Bar in 2004, Alastair ran a business consultancy which he had co-founded.
