Lawmakers in Zambia are to scrutinise the controversial maize export deal to Malawi.
The Zambian government denied any wrongdoing following allegations by Saviour Chishimba, an opposition leader without parliamentary representation.
Malawian president Peter Mutharika has however fired his agriculture minister George Chaponda, over the import of 100 000 tons of maize from Zambia.
Parliamentary speaker Dr Patrick Matibini on Thursday ordered Cornelius Mweetwa, a United Party for National Development member of parliament for Choma Central, to submit written questions, in order for Matabini to direct the executive to respond.
Mweetwa earlier complained to the speaker that Zambians needed to know exactly what transpired in the transaction which saw maize being exported to Malawi.
The Zambian Ministry of Agriculture denied corruption, but Chishimba insisted the export of maize to Malawi was corruptly orchestrated by politically connected individuals in the ruling Patriotic Front (PF).
