Davis joined the board in June 2024 and was appointed chair on an interim basis in February 2025 after the company’s chief executive Steve Hatch, who had been in the position for 18 months, stepped down by mutual agreement. At that point, YouGov co-founder and former chief Stephan Shakespeare returned as interim chief executive.

YouGov’s board has appointed Griffiths as permanent chair of the board, effective immediately. Griffiths joined the board in September 2025. He will take over as chair of the nomination committee and will remain a member of the audit & risk committee and the remuneration committee.

Griffiths was deputy chief executive and chief financial officer of Kantar between 2020 and 2022, and prior to that, led finance and operations at ITV. He is currently a currently a non-executive director for BBC Commercial and an independent non-executive director at Stanley Gibbons Baldwins. 

Belinda Richards, senior independent director, said: "On behalf of the entire board, I would like to express our deep appreciation to Deborah for her exceptional leadership and commitment to the company. Ian has already demonstrated the value he brings to the board through his industry knowledge and wealth of experience and I am confident that he will continue to deliver this in his enhanced role as chair."

Griffiths said: "Deborah has played an important role on the board, offering invaluable guidance during a period of significant change. We thank her for her unwavering dedication as she stepped in as interim chair last year, helping to stabilise the business. It is clear that Stephan has created a unique business and I very much look forward to partnering with him and the team in helping return this business to growth and delivering value for our shareholders."
