Niall is a partner and head of the EU, Competition and Regulatory Law Group.
He has extensive experience advising Irish and multinational businesses on all aspects of Irish and EU competition law, but particularly on complex merger control mandates.

His experience extends to both public and private deals, private equity and venture capital investments and to joint ventures and strategic alliances. Niall also advises on the new Irish foreign direct investment screening regime.
His behavioural competition law practice covers abuse of dominance, cartels and other restrictive arrangements, regulatory investigations, compliance issues and consequential litigation following on from allegations of breach of the competition rules. He has recently led multi-disciplinary teams on the highest profile competition law investigations in the jurisdiction.
Niall's broad practice has a particular focus on the energy, media & entertainment, insurance, agriculture & food, technology, sport and financial services sectors.
