An ombudsman is an official appointed to investigate complaints made by individuals against organizations, typically government agencies or large institutions. Their role is to ensure fairness and accountability, helping to resolve disputes through mediation and providing recommendations for improvement. Ombudsmen operate independently and are often seen as a bridge between the public and the organization. They gather information, conduct inquiries, and report findings, ensuring that people's concerns are heard and addressed. This role is crucial in promoting transparency and trust within public services and other sectors.
