The Muttahida Quami Movement's candidate Iqbal Muhammad Khan had won the National assembly seat (NA-256). Pakistan Tehreek-e-Insaf (PTI) candidate Zubair Khan later challenged the result in the election tribunal headed by a former judge of the Sindh High Court, Zafar Ahmed Sherwani, who ordered Nadra for verification of votes through thumb impressions on ballot papers.
Nadra report revealed that only 6815 of the total 84,748 ballots sent to Nadra for verification of certain polling stations were successfully authenticated. The report said that there were 11,343 ballot papers that contained invalid national identity card numbers, which were never issued by the Nadra. It also found that there were 791 votes which were not registered in the constituency and the fact was ascertained on the basis of the CNIC numbers mentioned on the used ballot papers. This bogus voting was observed in three different polling stations of the constituency.
Besides, the report said that there were 5839 duplicate votes, which were cast by as many as 2812 voters mainly in two polling stations. It said as many as seven votes were cast on one CNIC (42201-5796395-3) of Shakir Zaheer, a resident of Gulistan-e-Jauhar Block-13 Karachi.
