6. C ivil society groups and opposition parties are pushing for a review of the decision that was made by SA's Department of International Relations and Cooperation to grant Mugabe diplomatic immunity.

“If the review application is successful (and there are very good grounds to believe it will be) the doors will be open for the National Prosecuting Authrity to prosecute Mrs Mugabe,” said AfriForum chief executive Kallie Kriel.

7. AfriForum represented Engels and advocate Gerrie Nel, who secured the murder conviction of Oscar Pistorius, has taken the case.

8. Grace Mugabe has claimed that she hit Engels in an act of self-defense.

"She is adamant on the issue of protecting herself because she feels she was attacked. She says she was attacked by the victim and that she also has her own injuries which she is not going to publish in the media,” said one source.

9. This was not the first time she has been granted diplomatic immunity after an alleged assault abroad.

In 2009, the Chinese government gave her diplomatic immunity after she assaulted a journalist in Hong Kong.
