Turkey Election: Result too close to call as Erdogan fights to remain in power

Turkey could be set for a run-off presidential election with no clear winner emerging so far several hours after polls closed.

The parties of Tayyip Erdogan and opposition rival Kemal Kilicdaroglu are each claiming the lead.

Mr Erdogan has been in power for 20 years but is facing the biggest threat to his political supremacy since becoming president.
