The Police and Crime Commissioner for Cleveland, Barry Coppinger, has announced he will not stand for re-election next year.
It follows a damning report on Friday which named Cleveland Police as the first force in the country to be rated inadequate across all areas examined by inspectors.
Mr Coppinger has been in his post since the role of Police and Crime Commissioner was created in 2012.
Police and Crime Commissioner elections are due to take place across the country in May 2020.
