Key Takeaways

  • GREF has restructured its Board with two senior departures and two appointments.
  • Tim Miller (ex-UKGC) and Jean-Michel Costes (ex-ANJ) have both stepped down from the GREF Board.
  • Ian Angus, Director of Policy at UK Gambling Commission, has been named GREF Treasurer.
  • Olivia Petit, Associate Professor at KEDGE Business School, now serves as GREF Board Secretary.

The Gambling Regulators European Forum (GREF) has revised its Board structure, marking the departure of two senior members and the appointment of new leaders. Tim Miller, previously of the UK Gambling Commission and former Treasurer of GREF, and Jean-Michel Costes, formerly of France's National Gambling Authority (ANJ), have both stepped down following their respective exits from their home regulatory bodies. The Board now welcomes Ian Angus, Director of Policy at the UK Gambling Commission, as Treasurer, and Olivia Petit, Associate Professor at KEDGE Business School, as Secretary.

Changes to GREF Board Leadership

GREF has announced a significant refresh of its Board. Tim Miller's exit comes after his recent departure from the UK Gambling Commission. Miller had served on the GREF Board for several years, including a key period as Treasurer. The organisation credited him for his "expertise, leadership and commitment to international regulatory cooperation." The Board formally recognised his contribution and conveyed its thanks as well as best wishes for his future endeavours.

In parallel, Jean-Michel Costes has also left the GREF Board, a change triggered by his stepping down from his position at the Board of France's National Gambling Authority (ANJ). The Board extended its appreciation for Costes’ “dedicated service” and acknowledged his efforts in advancing the forum’s regulatory mission.

Treasurer Role Passes to Ian Angus, UK Gambling Commission

With Miller's departure, GREF has appointed Ian Angus, Director of Policy at the UK Gambling Commission, as its new Treasurer. Angus brings a background in gambling regulation and public policy, underlining a continuity of UK representation in GREF’s financial and operational oversight. The Board highlighted his “extensive experience in gambling regulation and public policy,” and expects his appointment to reinforce GREF’s commitment to robust governance and collaboration among European regulatory authorities.

Appointment of Olivia Petit as Secretary

GREF has also selected Olivia Petit as Secretary to the Board. Petit is Associate Professor at KEDGE Business School, where she researches consumer behaviour, digital environments and emerging technologies. Her appointment introduces an academic perspective to the forum—especially as advances in digital consumer engagement and technology shape the regulatory agenda across the European iGaming sector.

GREF’s Mission and the Context of Board Changes

GREF acts as an international forum for gambling regulators seeking cooperation, dialogue and knowledge exchange across Europe and other jurisdictions. The rotation of board members typically follows changes within national regulatory agencies, reinforcing the Forum’s alignment with its members’ home markets. Appointing leaders from the UK Gambling Commission and academic circles illustrates GREF’s aim to blend regulatory discipline with contemporary research on digital markets.

“Tim has been a valued member of GREF for many years, making a significant contribution through his expertise, leadership and commitment to international regulatory cooperation,” the GREF Board noted in its formal statement.

The Board’s recent decisions reiterate its goal of representing a range of European voices and experiences, from regulatory practitioners to researchers focused on the digital evolution of gambling. For professionals in the regulation and b2b segments, board composition can shape priorities around policy coordination, cross-border standards, and industry innovation.

Outlook for GREF and the European Regulatory Community

With Ian Angus as Treasurer and Olivia Petit as Secretary, GREF signals its continued commitment to effective governance, knowledge-sharing, and implementation of best practices across its network. Ongoing changes in the wider gaming sector—including shifts in consumer behaviour and digital technology—make GREF’s organisation and leadership composition relevant for both local and pan-European regulatory strategies.
