The Riyadh agreement, signed by the Southern Transitional Council (STC), President Abd Rabbuh Mansour Hadi's government, and their Saudi and Emirati backers, was announced on 5 November by Saudi Crown Prince Mohamed bin Salman.
According to the deal, the STC will be part of a new cabinet and tens of thousands of UAE-backed southern forces will be placed under Yemeni government control.
The deal stipulates that within 30 days, the two sides should form a new government of no more than 24 ministers, with 50 percent STC and southern representation.
Hadi would maintain control on key ministries, including interior and defence, while the STC would get two portfolios.
The STC will also be included in political negotiations to end the war against the Houthi movement.
All military forces, the deal stipulates, shall be placed under the defence ministry, while security forces would be under the control of the interior ministry.
Within 15 days, all forces deployed in the south since August should return to their previous positions, and medium and heavy weapons are to be handed over under coalition supervision.
Within 30 days, government and STC military forces should leave Aden and Saudi Arabia’s military is to oversee security in the city.
