An inquiry into whether Carwyn Jones misled the assembly over claims of a bullying culture in a previous Welsh Government has found he did not breach the ministerial code.
James Hamilton said he found no evidence Mr Jones saw allegations of bullying by special advisors.
Answers given by the first minister were accurate and truthful, he said.
Mr Jones was accused of misleading AMs when he said no allegations of bullying were made in 2014.
Claims of bullying allegations that year emerged following the death of Carl Sargeant, who died days after Mr Jones sacked him from his cabinet.
Mr Jones referred himself to an independent inquiry after he was accused of misleading the assembly when he said no one at the top of this government had complained about bullying in 2014.
