Recep Tayyip Erdogan - President of Turkey

For a special edition of HARDtalk, Zeinab Badawi is in the Turkish capital of Ankara to speak to the country's president Recep Tayyip Erdogan. He is busy preparing for elections which he has called a year and a half early. Is he trying to pre-empt a possible slide in his popularity, or simply trying to tighten his grip on power? How worried is he about escalating tension in the Middle East following Donald Trump's decision to pull out of the Iran nuclear deal?
