Freshfields Bruckhaus Deringer has appointed two partners in its Brussels office – part of a promotion round of 22 lawyers, the firm's largest since 2008.

Tone Oeyen, who is Belgian, specialises in European and Belgian competition law with a particular focus on cross-border merger control and cartel enforcement. He also advises on abuse of dominance and state aid, as well as on general EU and international trade law and trade defence measures.

He has worked on remedies and anti-competitive behaviour in areas affected by digital transformation, and has defended clients in cartel and state-aid related litigation.

Recently, Oeyen has worked on a number of high-profile cases, including advising Siemens in its unsuccessful bid to win regulatory approval for its merger with Alstom. He also advised Boehringer Ingelheim on its $22 billion asset swap with Sanofi, and Solvay on its $5.5 billion acquisition of Cytec Industries Inc. and its joint venture with INEOS.

The other newly appointed Brussels partner, Frédéric Elens, also Belgian, specialises in cross-border acquisitions and divestments, joint ventures, reorganisations, carve-outs and other corporate transactions. He advises Belgian and international private equity and financial investors, corporate clients and financial institutions. Elens' expertise spans both private and public M&A transactions and covers a wide range of industries. Alongside his transactional practice, Elens advises clients on corporate advisory, company law and governance matters.

His recent work includes advising Vendis Capital Management on the sale of the Inula Group to Ardian, IK Investment Partners on its acquisition of CID Lines, and the acquisition of Meratech. Elens' other clients include CVC Capital Partners, which he advised on the sale of Praesidiad, and Cinven on its acquisition of One.com.
