Higher and Tertiary Education minister Jonathan Moyo yesterday outed President Robert Mugabe's spokesperson George Charamba as the shadowy Herald columnist Nathaniel Manheru.
Moyo has in the past revealed that he ran the column in his first stint as Information minister before it was inherited by Charamba.
However, Charamba has not publicly admitted that he is the author of the column, where threats against independent journalists are routinely made.
Manheru recently ruffled feathers when he wrote a piece attacking Vice-President Emmerson Mnangagwa's opponents in Zanu-PF who he alleged had joined hands with former vice-president Joice Mujuru.
Moyo last week also took issue with the Herald's reportage on Zanu-PF factionalism and chastised the paper for making reference to the "anti-Mnangagwa cabal in Zanu-PF".
Yesterday the former Information minister seemed to be going for the jagular when he mentioned Charamba by name as he responded to issues raised by Manheru on Twitter.
"Yes Cde Charamba a new education curriculum must be about a new history and a new narrative," Moyo tweeted.
"Its content, stupid," he added before providing a link to the article titled New Curriculum: History The Temptress.
Moyo and Charamba have had an uneasy relationship since the time the political scientist headed the Information ministry for the first time in 2002.
The minister's latest revelation would bolster allegations that Charamba is involving himself in the partisan wars to succeed Mugabe while using State-controlled media.
