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.

Vanda Murray OBE, Chair of the Board, commented:

"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.
