Dianne has worked in the UK public and not for profit sector for over 40 years, for much of that time at board level. She spent 20 years in local government as a public sector lawyer and manager, then joined the then National Assembly for Wales, to take on a variety of leadership roles, focussing on operational and strategic management.
Dianne has high-level knowledge and experience in public sector law and governance, change management, and the establishment of new frameworks for major institutions. She led significant change projects arising from local government reorganisation in Wales, devolution and the resulting institutional transformation.
In June 2022 Dianne was appointed as a Local Democracy and Boundary Commissioner for Wales, considering local electoral boundaries, and as legislation is made, representation and constituencies in Wales, ahead of Senedd (Welsh Parliament) reform and expansion.
Dianne holds several voluntary and non-executive board positions and occasional consultancy in the public, parliamentary and not for profit sector. She is a member of the board of the Hansard Society, a research and education charity, which works to strengthen parliamentary democracy and engagement in politics. With Global Partners Governance, Dianne has worked on several projects in Jordan, advising and supporting the Parliament, civil service and local government.
