Former Nationals leader Barnaby Joyce says he didn't pursue Scott Morrison's increased secret powers because he thought his party would lose the extra portfolio they had gained.
Mr Joyce said he was never explicitly told by Mr Morrison that the former prime minister had appointed himself as resources minister, but eventually found out "obliquely".
Mr Morrison took on the health, finance, treasury, home affairs, industry, science, energy and resources portfolios between March 2020 and May 2021.
