The vice chairman of the executive board of Turkey's Kalyon Group, Haluk Kalyoncu tied the knot late Saturday with Yelda Demirören, daughter of Demirören Group's board chairman Yıldırım Demirören.

President Recep Tayyip Erdoğan and first lady Emine Erdoğan attended the wedding ceremony held at Istanbul's lavish Çırağan Palace as witnesses, while the mayor of the Istanbul Metropolitan Municipality Mevlüt Uysal officiated the marriage.
