Michael has a busy practice across all of Chambers’ core areas, with a particular focus on Competition law (EU and UK), judicial review, freedom of information and sports law. He is a member of the Attorney-General’s C-Panel. He has appeared as sole counsel in the High Court (in each of the Chancery Division, Queen’s Bench Division, Administrative Court, Commercial Court and Mercantile Court), the Competition Appeal Tribunal, the Upper Tribunal, the First-tier Tribunal and a range of country courts. He also regularly works alongside other barristers as part of a legal team, often in complex, high-value litigation.

Michael has a broad and diverse practice: he regularly acts for both claimants and defendants, with clients ranging from major international businesses and central government departments to charities and individuals in receipt of legal aid. He is also happy to accept pro bono instructions in suitable cases.

Before qualifying as a barrister, Michael read Philosophy, Politics and Economics at Balliol College, Oxford, where he received the top mark in the University in Philosophy finals, and the 4th highest overall mark in the University. He then worked as a parliamentary researcher and caseworker in the House of Commons before completing his GDL (with Distinction) and BPTC (Outstanding, ranked 5th in year) at City University, London.


  • Competition Law and Commercial Regulation

    Competition law

    Michael’s competition law practice covers litigation and advisory work across the full spectrum of EU and UK competition law, with a particular emphasis on standalone and follow-on cartel damages claims and private abuse of dominance claims.

    He is currently instructed on some of the most of high-profile competition claims in this jurisdiction, including:

    • Acting (as junior to Jon Turner QC) for British Airways in the “air cargo” cartel damages litigation in the Chancery Division.
    • Acting (as junior to Marie Demetriou QC) for one of the defendants in tcartel damages claims brought by National Grid and Scottish Power in the Chancery Division following the European Commission’s Power Cables cartel decision.
    • Acting for the proposed defendant in Dorothy Gibson v Pride, the first claim brought in the Competition Appeal Tribunal under the new collective proceedings regime introduced by the Consumer Rights Act 2015.

    Michael’s previous competition law litigation experience includes acting for the successful claimant in a private abuse of dominance claim, culminating in a three-week trial in the Chancery Division:  Arriva The Shires Ltd -v- London Luton Airport Operations Limited [2014] EWHC 64 (Ch).

    Michael is a published author in one of the leading academic journals in this field (“Competition Law, land agreements and the decision in Martin Retail Group Ltd v Crawley Borough Council: an opportunity missed?”, Competition Law Journal (Vol 11, issue 3, 2014)).
