Arnold & Porter Expands European Antitrust Litigation Team with Addition of Partner Nicola Chesaites
LONDON and WASHINGTON, D.C., May 5, 2026 — Arnold & Porter announced today that Nicola Chesaites has joined the firm’s Antitrust/Competition litigation practice as a partner, resident in London.
Kathleen Harris, head of Arnold & Porter’s London office, said: “Nicola is widely recognized as a leading competition litigator and for her skill in navigating complex litigation risk and strategic advisory work. Her arrival strengthens our robust competition and commercial litigation practices. She will be a great addition to Arnold & Porter’s London team.”
Niels Christian Ersbøll, Global Co-Chair of Arnold & Porter’s Antitrust/Competition practice group and head of the Brussels office, added: “Nicola’s unique dual qualification as both a barrister and a Belgian advocate will be a significant asset, enhancing our ability to support clients across the UK and EU in their cross-border antitrust matters and interconnected litigation, regulatory, and transactional needs. We are delighted to welcome her to the firm.”
Nicola is a UK-qualified barrister and a Belgian advocaat with more than 17 years of experience in competition damages litigation, collective (class) actions under the UK’s private enforcement regime, and complex European Union litigation. She has represented claimants and defendants before the English courts and the UK Competition Appeal Tribunal, and appeared before the EU General Court and Court of Justice on behalf of corporates and EU institutions in a range of EU law disputes ranging from banking resolution, trade, sanctions, pharmaceuticals, and transportation disputes.
In joining the firm, Nicola said: “As regulatory regimes evolve and with the increase in private enforcement of competition law in Europe, and the rapid growth in collective actions in the UK, litigation risk is increasingly complex for clients active in multiple markets. Arnold & Porter’s integrated platform and global footprint make it an ideal environment for my practice and I look forward to collaborating with colleagues in Europe and globally to provide clients with advice on their antitrust, regulatory, and litigation risks.”
Nicola holds an LL.M. from the College of Europe, an LL.B. from the University of Westminster, and a License in French Law from Université Paris X Nanterre.
