Who is the leader of OIC?

The Organization of Islamic Cooperation (OIC) does not have a single leader, as it is made up of member states that each have their own leaders. The OIC is governed by the Council of Foreign Ministers, and its presidency rotates among member states every three years. As of my last update, the Secretary-General of the OIC is Hissein Brahim Taha, who took office in November 2021. For the most current leadership details, please refer to the OIC's official website or recent news updates.
