In July, Zain Qureshi, son of former foreign minister Shah Mahmood Qureshi, and a member of the national assembly, contested a provincial constituency in Multan, Punjab.
After his thumping victory, he took oath of the Punjab assembly, thereby vacating his seat in the national assembly.
That left NA-157 up for grabs. Now, a by-election will be held, on September 11, in Qureshi’s former constituency in Multan.
