“No such meeting took place on Monday with either the president or anyone representing him‚” Ngqulunga added.
The Sunday Times reported that Zuma reshuffled his cabinet after meeting a delegation from the Russian government last Monday.
Government insiders said the group came to warn Zuma to implement the R1-trillion nuclear build project.
Zuma made a number of changes to the cabinet‚ including moving Mmamoloko Kubayi from the energy portfolio and replacing her with former state security minister David Mahlobo.
Reports have said that Mahlobo received training in Russia in 2014 and visited the eastern European nation recently to facilitate a business deal with exploration company Rosgeo.
