The chief executive of the Local Government and Social Care Ombudsman will retire in May.
Nigel Ellis held the role for eight years, during which time he worked alongside six ombudsmen.
He was previously the organisation’s director of operations.
Mr Ellis said: ‘I believe the organisation is in a strong position and, along with the ever-present challenges, there are genuinely exciting new opportunities that lie ahead.
‘There is still much for me to do in the coming months and I look forward to ensuring the organisation continues to be efficient and effective in its role as part of the oversight system for local government and social care.’
Recruitment for a new chief executive will begin soon, and it is expected that an an appointment will be announced early next year.
