Egypt's interim president has issued a decree reshuffling the country's top military council and installing for the first time the military chief as its leader.

Adly Mansour's decree Thursday is part of series of declarations related to rearranging the country's sprawling security establishment nearly two months before presidential elections. It puts the military chief — now Field Marshal Abdel-Fattah el-Sissi — in charge of the council.

El-Sissi must step down before his widely expected run for president. The next army chief would take his council spot.

The decree also rearranges and increases the number of members of the country's Supreme Council for Armed Forces, which led the country after the overthrow of Hosni Mubarak in 2011.

El-Sissi led the July overthrow of Islamist Mohammed Morsi, Egypt's first freely elected president.
