Sinan Oğan, who came third with 5.17% of presidential vote, says second-placed Kılıçdaroğlu failed to offer a convincing alternative to incumbent
The nationalist candidate who can third in the first round of the Turkish presidential elections has formally endorsed Recep Tayyip Erdoğan, with the runoff vote to be held on 28 May.
Sinan Oğan, 55, emerged as a potential kingmaker after neither Erdoğan nor his main challenger, the opposition leader Kemal Kılıçdaroğlu, secured the necessary majority in the first round on 14 May.
