Directorate team

The Board of Trustees delegates to the Chief Executive the management of Christian Aid.

The Chief Executive has authority to direct the charity’s staff, resources and relationships in line with the overall strategic policies, direction, goals and budget set by the Board of Trustees and in keeping with constitutional objectives, the essential purpose, identity and nature of Christian Aid.

The Chief Executive leads the executive group, known as the ‘Directorate’. The Directorate operates in a collegiate manner, as a team.

The Chief Executive however, as the chairperson, has ultimate authority over any decisions made within the Directorate. The Heads of Department (‘Directors’) have authority to lead their departments in line with the priorities collectively agreed by the Directorate.
