With reference to the supposed non-security additions at the homestead of the President, Mr J G Zuma, in Nkandla, did his department, at any stage, ask for an explanation why the Security Cluster ordered (a) a swimming pool, (b) a chicken run, (c) a cattle kraal, (d) the shop, (e) air conditioning, and any of the other non-security related upgrades at the private home of the President, Mr J G Zuma; if not, why not: if so, are there any letters which could be provided as proof in this regard?
