I kind of disagree with Gareth on this one....
There is speculation about why he has been axed, beyond that nothing in the public domain is concrete.
If he did axe the Deputy Minister for going to the US after being warned not to, then the DA needs to very publicly demand accountability from Cyril for the Ministers who have lied and all that... and make sure that whats good for the goose is good for the gander as well.
Also questions would need to be asked about the Deputy Minister and the trip to the US and whether it was taken whilst on leave from his official duties and who paid etc.
