Turkey's Nationalist Movement Party (MHP) expelled former Iğdır deputy and intra-party opposition figure Sinan Oğan from party membership citing his recent comments criticizing party leadership and a possible poor performance in snap elections.MHP's Central Disciplinary Committee unanimously voted to expel Oğan on Wednesday.Oğan was critical of party's performance and stance in June 7 general elections, and his tweets criticizing MHP's performance in Istanbul, which fell behind the party's arch rival pro-Kurdish Peoples' Democratic Party (HDP) performance, were exceptional in MHP known for its rigid leadership structure.An influential figure in party's voter base, Oğan was not nominated by MHP in June 7 elections.He later warned that MHP may not pass the 10 percent national election threshold in a possible snap election.
