Notice the controlled reporting. They have not even mentioned the real reason he gave for leaving the seat. He said that PTI had won this seat but it was given to him through rigging and they completely omitted that part
Intraparty elections happened in May 2022. EC deliberately gave decision at the last moment. The question that Qazi needed to ask was if EC was sleeping since May 2022 but he conveniently ignored this fact in his decision.
They don't need a portal really. A simple PDF file with list of candidates and their symbols will suffice. They can post it in PTI official twitter and Facebook.
The portal was working fine first few hours after launch because I checked it myself then after a few hours I noticed that it stopped showing candidates and their symbols for most constituencies.
