The Independent correspondent Şebnem Arsu comments on the role of social media and fake news in the run-up to the June 23 mayoral vote in Istanbul, as well as the escalating tension between Ankara and Washington over Turkey’s purchase of the Russian S-400 air defense system. Arsu underlines that the ruling AKP’s complete takeover of the mainstream media is pushing the CHP candidate Ekrem İmamoğlu to embrace social media.
