President Cyril Ramaphosa will have to explain to the National Council of Provinces (NCOP) the circumstances which led to him approving Defence and Military Veterans Minister Nosiviwe Mapisa-Nqakula's controversial visit to Zimbabwe last month.

Ramaphosa will be answering questions in the NCOP on Tuesday. The virtual sitting is scheduled to start at 15:00.

One of the questions, by Democratic Alliance (DA) whip in the NCOP Cathlene Labuschagne, deals with the flight, which saw civilians and high-ranking African National Congress (ANC) officials – Ace Magashule, Nomvula Mokonyane, Enoch Godongwana, Dakota Lekgoete and Tony Yengeni – on a South African air force plane along with Mapisa-Nqakula and Minister of Social Development Lindiwe Zulu.

After a public outcry, Ramaphosa demanded answers from Mapisa-Nqakula.

He eventually sanctioned her by docking three months of her salary.

The presidency also published the documentation provided by Mapisa-Nqakula.

According to the documentation, on 7 September, Mapisa-Nqakula asked her Zimbabwean counterpart Oppah Muchinguri-Kashiri for a meeting, which would take place on 9 September in Harare.

Muchinguri-Kashiri, who also is the chairperson of Zanu-PF, agreed in writing on the same day.

Also, on 7 September, Mapisa-Nqakula requested approval for the trip from Ramaphosa.

The ministerial handbook requires ministers to request approval for international visits at least two weeks before departure.

Mapisa-Nqakula and her entourage left South Africa on 8 September.

Included in the documents provided by Mapisa-Nqakula is a letter from principal state law advisor Geofrey Mphaphuli, in which he granted permission for the visit. The letter is dated 10 September.

Subsequent to News24 reporting that approval was granted only after Mapisa-Nqakula returned, the presidency issued a statement – it said Ramaphosa gave verbal approval for the visit on 8 September, the same day Mapisa-Nqakula and her fellow travellers left South Africa.

Furthermore, it is clear Ramaphosa knew of a pending visit by ANC officials to Zimbabwe.

On 31 August, Ramaphosa, speaking after an ANC NEC meeting, said: "The secretary-general [of the ANC, Ace Magashule] will be finalising the delegation that will be going to Zimbabwe in days, to meet with the Zimbabwe governing party, Zanu-PF."

Labuschagne wants to know when Ramaphosa was first informed of the flight, on what grounds he approved it, and whether he was informed that a delegation of a "certain political party" was included on the flight at the time of approval.

Ramaphosa will also have to answer two questions related to Covid-19 corruption, as well as questions on gender-based violence, the financial sustainability of municipalities and the damage caused to the public rail system during the Covid-19 pandemic.

The question session was originally scheduled for 15 October, but Ramaphosa called a joint sitting of Parliament on that date to present his economic recovery plan to both houses of Parliament.
