Far-right nationalist holds key to Turkey's political future.

Sinan Ogan, Turkey's nationalist presidential candidate who finished third in Sunday's election, said he could only support main opposition candidate Kemal Kilicdaroglu in the runoff if he agrees to offer no concessions to a pro-Kurdish party. Ogan won 5.2% in Sunday's first round of the presidential election, emerging as a potential kingmaker after the May 28 runoff vote. Ogan said his goal was to remove two mainly Kurdish parties from Turkey's "political equation" and bolster Turkish nationalists and secularists.
