The involvement of MQM chief Altaf Hussain, PTI Chairman Imran Khan and JI chief Sirajul Haq had turned what was just a simple by-election for one seat into an electoral battlefield of national importance.

213 polling stations were set up with 769 polling booths housed in 55 buildings, for 357,861 registered voters. Around 2,556 policemen will provide security in the constituency, whereas Rangers personnel were also deployed at almost all polling stations.
