When residents believe that their local council has made the wrong decision on an issue, or failed to adequately support them, a complaint can be lodged with the Local Government Ombudsman (LGO). The Ombudsman will investigate the complaint in those instances where it has the scope to do so, and will either dismiss or uphold the complaint depending on whether the authority acted correctly. You can find out more about what the LGO does here, along with specific examples of some of the most shocking cases.
These are the local authorities in England which had the most complaints against them upheld in the year 2019/2020.
