Good start for the dynamic duo.
On the slow pace they are releasing the names, I must concur its quite annoying. There are however no constitutional timelines for naming of Cabinet secretaries and from my recollection, the two have never promised to name a cabinet by any given time. All we have relied on timings are just the 'credible sources' from our beloved media houses.
I also tend to agree with those that have noted that you don't have to be a medic to head Afya House. The Cabinet secretary is a policy maker concerned with strategy formulation and resource allocation and performance management. FYI, the GB Chancellor of the Exchequer (our National Treasury) actually studied Modern History. Yes, check it out.
Hope the rest of the names come sooner...
