Electoral fraud claims and political violence caused controversy in the run-up to the election . Several candidates and party offices were subject to politically motivated attacks , culminating in the death of four HDP supporters after two bombs exploded during a rally in Diyarbakır on 5 June . The interference of President Erdoğan , who was accused of covertly campaigning for the AKP under the guise of ' public opening ' rallies , was also controversial since the President is constitutionally required to exercise political neutrality . Despite fraud claims dating back to the hugely controversial 2014 local elections and numerous claims of misconduct on polling day , the election was largely praised by the Organization for Security and Co-operation in Europe for being well-organised and was declared free and fair by the European Parliament
