Bülent Arınç resigns from the membership of Turkey's Presidential High Advisory Board

His resignation comes after Turkish President Recep Tayyip Erdoğan slammed him a day before, as he urged the release of jailed businessperson Osman Kavala and former HDP co-chair Selahattin Demirtaş.

Bülent Arınç, along with Recep Tayyip Erdoğan, co-founded the Justice and Development Party on August 14, 2001.

Bülent Arınç served as the 22nd Speaker of the Parliament of Turkey from 2002 to 2007 and as a Deputy Prime Minister of Turkey between 2009 and 2015.  (ILKHA)
