Erdogan’s daughter Sumeyye married defence industrialist Selcuk Bayraktar at a large-scale and high security ceremony in Istanbul.
Prime Minister Nawaz Sharif signed the wedding document as a witness. He was called with request to put his signature for the purpose by the Mayor of Istanbul at the beginning of the function.
The wedding started with the reciting of Quran, the private NTV television reported.
Top officials including Prime Minister Ahmet Davutoglu, army chief Hulusi Akar and former president Abdullah Gul attended the ceremony, to which some 6,000 guests were reportedly invited.
Foreign leaders including Pakistani Prime Minister Nawaz Sharif were also in attendance.
Davutoglu’s appearance at the wedding could dismiss claims of a split with the president.
In a surprise move, Davutoglu last week announced he would step down as premier and leader of the ruling Justice and Development Party (AKP) at a congress later this month.
