President Goodluck Jonathan on Friday morning returned to Abuja after attending the D-8 Summit in Islamabad, Pakistan.
The president, who left Abuja on Wednesday night, attended the opening session of the Summit of the Heads of State and Government of the D-8 on Thursday.
He also participated in the activities of the Summit, as the outgoing Chairman of the Organisation.
Jonathan later handed over the chairmanship of the organisation to the host, President Azif Zardari, who chaired the meeting of the summit.
The summit deliberated on the theme "Democratic Partnership for Peace and Prosperity" and endorsed the D-8 Charter and the D-8 Global Vision.
The News Agency of Nigeria (NAN) recalls that Jonathan took over the leadership of the body in April 2010 when Nigeria hosted its 7th bi-annual summit.
This is in line with the organisation's statute.
On the sidelines of the summit, the president held bilateral meetings with the leaders of some member countries and also met with the Nigerian communities in Pakistan.
The D-8 was established in 1997 in Istanbul, Turkey, to promote development cooperation among member countries.
The members are Nigeria, Pakistan, Malaysia, Turkey, Egypt, Indonesia, Bangladesh and Iran.
