AXED national police commissioner Bheki Cele could continue to make headlines this week, after saying he would be approaching the courts in a bid to get clarity on the reasons for his dismissal.

And all eyes will be on new police chief Mangwashi "Riah" Phiyega as she enters her first full week as commissioner. Gen Phiyega's appointment was criticised by some as she has no policing experience.

President Jacob Zuma fired Mr Cele last week, citing a commission of inquiry led by retired judge Jake Moloi, which found him to be unfit for office. The commission was set up after Public Protector Thuli Madonsela had investigated police headquarters lease deals. She had found Mr Cele's involvement to be "improper, unlawful, and (amounting) to maladministration".

Mr Cele last week said he wanted the courts to declare the report by the commission of inquiry "factually and legally unsound". He is expected to file his application by the end of this week.

The Democratic Alliance (DA) said yesterday there were sufficient grounds for Mr Cele to be criminally investigated. DA police spokeswoman Dianne Kohler Barnard said the party believed the evidence gathered and investigations conducted by both the board of inquiry and the public protector were sufficient for instituting criminal charges against the embattled former policeman.

Mr Cele's sacking could also have implications for Mr Zuma's bid for a second term as African National Congress (ANC) president. Reports emerged on Friday that some ANC senior members in KwaZulu-Natal, Mr Zuma's home province, were unhappy about Mr Cele's sacking. KwaZulu-Natal is the source of most of the ANC's votes and Mr Zuma normally enjoys great support in the province.

Mr Zuma will today be in Los Cabos, Mexico, to participate in the Group of 20 (G-20) summit. He is accompanied by Finance Minister Pravin Gordhan. Undoubtedly, the euro-zone debt crisis will top the two-day meeting's agenda.

The Department of International Relations and Co-operation says SA will use the summit to promote the G-20's development agenda, and highlight issues such as support for infrastructure development in SA and on the continent.

On Wednesday, after the conclusion of the summit, Mr Zuma will proceed to Rio de Janeiro for the United Nations' Rio+20 sustainable development conference.

The ANC in the Free State is likely to hold its elective conference later this week. This will pit incumbent provincial chairman Ace Magashule - who is said to be an ally of Mr Zuma - against Mxolisi Dukwana, who has been axed from his position as economic development MEC. Although the Free State is one of the smallest provinces in the ANC in terms of numbers, the outcome is likely to have a bearing on the elective conference in December. This is to take place in the province, in Mangaung.

Also worth watching this week is Ms Madonsela's draft report on a probe into the awarding of tenders by the Limpopo government to On-Point Engineering, a company linked to expelled former African National Congress (ANC) Youth League leader Julius Malema. According to Themba Mthethwa, CE in Ms Madonsela's office, the draft report is likely to be released this week.

The report could add to Mr Malema's woes. He is already being probed by the Hawks and the South African Revenue Service. Last week, the ANC's national executive committee said it had found no grounds to review the decision to expel the beleaguered former youth league president.

The DA will on Friday have its first "caucus breakaway" under parliamentary leader Lindiwe Mazibuko. The "caucus breakaway" will see MPs of the party meet in Stellenbosch to discuss and review their work in Parliament so far this year.
