Graham Prothero, our Senior Independent Director and Audit Committee Chair, has informed the Board that, after nine years with the Group, he wishes to retire from the Board at the end of Marshalls' 2026 AGM. Paul joins as Audit Committee Chair designate and will assume this role fully when Graham steps down next year. Graham and Paul will work closely together until Paul formally succeeds Graham. Paul will also join the Audit, Remuneration, Nomination and ESG Committees.

Diana Houghton, who joined the Board in 2023, has agreed to assume the role of Senior Independent Director, succeeding Graham Prothero in this role when he retires.

"The Board is delighted that Paul will be joining the Company as a Non-Executive Director and Audit Committee Chair designate. With Graham Prothero stepping down next year, Paul's appointment is part of our wider succession planning and ensures we have the skills and experience to support the execution of our strategy and maintain our commitment to responsible governance.

The Board would like to thank Graham for his significant contribution to the success of the Company, particularly in his capacity as Audit Committee Chair and Senior Independent Director. Graham's sector knowledge and experience have proved invaluable in helping the Board navigate a number of business challenges and changes to the governance landscape over recent years. Diana will take on the vital role of Senior Independent Director, with her board and industry experience providing the ideal foundation for this role."
