Allen & Overy (A&O) global corporate co-head Sietze Hepkema is set to retire from the partnership in January and take on an of counsel position at the firm.

Hepkema, who has played a significant role in the firm’s global management for more than ten years, will now work just two days a week at A&O. He will spend the remainder of his time in non-executive roles outside of law, as well as getting involved in teaching projects, including investigations into corporate mismanagement.
