Partner, Head of Competition & Public Procurement

Partner Ilkka Leppihalme heads the firm's Competition & Public Procurement practice.

Ilkka's main area of expertise is EU and Finnish competition law. He also represents clients in litigation and arbitration proceedings and advises on mergers and acquisitions and various commercial contracts.

His competition law work covers the full spectrum of competition law (merger control, cartel investigations, horizontal and vertical agreements, abuses of dominance, litigation/damages cases, compliance programs and training, public procurement and state aid) across a wide range of industries.
