Nawaz Sharif, a Pakistani business magnate and politician, who has served the country as its Prime Minister thrice and three of those times have not been smooth.
The NA-120 seat in Lahore, said to be the stronghold of the Sharifs, fell vacant on July 28 after the Apex court disqualified Sharif in the Panama Papers case.
Maryam said dozens of PML-N activists were blindfolded and picked up from their homes at night, while others received threatening phone calls from unknown numbers during the campaign.More news: Education Secretary DeVos hopes schools 're-examine what they're doing'
According to the unverified and unofficial results being shared by DawnNews, a close contest is being observed between PTI's candidate Dr Yasmin Rashid and PML-N's Kulsoom Nawaz - with no one claiming a considerable lead as yet. The Election Commission of Pakistan is expected to announce the final and official result in a day or two.
On Sunday night, after winning the battle of NA-120, she addressed the workers in an emotional cum enthusiastic manner criticising her political opponents while PML-N workers chanted slogans of "I Love You Nawaz Sharif".
Long queues formed outside polling stations in the city on Sunday morning.
"The Sharif family doubts that it will get justice in the NAB cases, therefore there is no point in appearing before the accountability court", he said.
Advocate Ishtiaq Ahmad Chaudhry of the Pakistan Awami Tehreek (PAT), PPP's Faisal Mir and Nabeel Shahzad of the Milli Muslim League (MML) had filed the petitions in the High Court. The opposition also said that the margin of PML-N victory is in fact a defeat of the powerful Sharif family.
