Papua New Guinea's Fisheries and Marine Resources Minister Mao Zeming said Sir Mekere Morauta's record in government was not as rosy as he was painting in paid advertisements on social media.
Mr Zeming was responding to Sir Mekere saying he is considering running for parliament this June.
Mr Zeming told the Post Courier he was part of the Morauta government until 2002 and he saw first-hand the messy and disorganised government he ran.
He says Sir Mekere refused the advice of his ministers and reshuffled his cabinet more than any other time since 1975.
Mr Zeming said he downsized our police force and defence force, to the detriment of our law and order and national security.
