“We have video evidence of rigging by MQM,” the PSP chief said while talking to the media in Karachi.

On Thursday the by-elections were held in Karachi’s Landhi and Korangi areas after a National Assembly seat fell vacant upon the death of MQM-P’s Iqbal Muhammad Ali Khan in April.

MQM-P’s Muhammad Abu Bakar has won the by-polls, according to unofficial results.

Kamal alleged that Cantonment Board elections were also stolen, adding the by-election had also been snatched from them.

He said that all parties should bring their voters and count them.

He accused TLP chief Saad Rizvi of attacking the PSP election office and killing a party worker. “But did not retaliate,” he added.

Both leaders of Tehreek-e-Labaik Pakistan and Pak Sarzameen Party were hurling accusations at each other of firing that left one PSP worker dead and injured several others during the polling.
