Cde Mnangagwa takes over from Zambia's Professor Geoffrey Lungwangwa as his country prepares for its own elections. The Southern African Regional Caucus comprises countries in the SADC region.
Issues that have continued to dominate debate at the session include human and women rights, ratification of the revised PAP Protocol and the quest to create a self sustaining budget for the PAP.
Earlier on this Wednesday morning, PAP president Hon. Roger Nkodo Dang presented his report on the state of the PAP covering the period from October 2005 to May 2016.
The PAP president applauded the oneness that has seen African legislators move together. "My gratitude also goes to all parliamentarians of the Pan African Parliament who through their activities at the Plenary within Permanent Committees or by representing the Pan African Parliament has enabled our assembly to rise from its ashes," said Mr Dang.
The Pan African Parliament, an organ of the African Union, is still grappling with the challenge of ratifying it's revised protocol.
According to President Dang's report, since its adoption by the Conference of Heads of States in June 2014, in Malabo Equatorial Guinea, the protocol has been signed, ratified and deposited by a single member state.
