Etyen Mahçupyan - Former Senior Adviser to Turkey's Prime Minister

Shaun Ley speaks to Etyen Mahçupyan, the former senior adviser to Turkey's prime minister. Recep Tayyip Erdoğan has dominated Turkish politics, first as prime minister now as president, for more than a decade. Last week, his Justice and Development Party, known as AK, lost its parliamentary majority. With it went Mr Erdogan's dream of a more powerful presidency. Etyen Mahçupyan was until recently his senior adviser. Does he see the result as a verdict on the president's authoritarian streak, his intolerance of dissent, anger over corruption or a stuttering economy? Etyen Mahçupyan says AK will win many more elections to come - but will President Erdogan?
