President Sata has transferred Home Affairs Minister Edgar Lungu to the Ministry of Defence in the same capacity.
Home Affairs Deputy Minister Dr Ngosa Simbyakula is the new Home Affairs Minister.
State House Spokesperson George Chellah announced the changes to Journalists at State House this afternoon.
The changes are with immediate effect.
The mini reshuffle has been necessitated by the resignation of Mr Mwamba as Defence Minister.
Earlier today, National Revolution Party President Cosmo Mumba advised President Sata to reject Geoffrey Mwamba’s resignation from cabinet.
Dr Mumba told a media briefing in Lusaka that President Sata should reject Mr Mwamba’s resignation because it is illegal.
He said Mr Mwamba’s resignation cannot be taken seriously because he has not written to President Sata over his decision to quit as Defence Minister.
Dr Mumba observed that the resignation of Mr Mwamba could pose risks to national security.
“We are asking His Excellency to reject GBM’s resignation. Let him rescind his decision because it is illegal in the first place. How does the Defence Minister resign just by word of mouth without even talking to the President first?” Dr Mumba said.
He added, “GBM’s resignation remains illegal as long as the President is not officially written to and if GBM finally writes, we want the President to out rightly reject the resignation in the interest of national security.”
Dr Mumba said his party finds it difficult to believe the reasons advanced by Mr Mwamba for his resignation.
“We think the issue of Paramount Chief Chitimukulu should not be issued to divide the nation and the PF. We want to believe that the reasons for GBM’s resignation stretches further than what he has stated. We want him to state the real reasons in the letter he will write to President Sata,” Dr Mumba said.
Dr Mumba however advised Mr Mwamba to rescind his decision and return to cabinet.
