The Saudi king has ordered a shake up of the country's top religious institution and advisory councils in a series of royal decrees.

According to the state news agency SPA, King Salman on Friday also ordered removal of the minister of labor Mofreg al-Haqbani and replaced him with Ali Ghafis.

The reshuffles affected the country's top religious body known as the Council of Senior Scholars composed of 21 members.

The king also ordered a shakeup of the 150-member Shura Council, keeping the number of women at 30. In 2013, the former Saudi King Abdullah had granted women seats on the council for the first time.
