According to unofficial estimates, Kulsoom Nawaz won the election for NA-120 seat by bagging more than 61,000 votes, defeating her PTI rival Dr Yasmin Rashid with a margin of over 13,000 votes. Election authorities will announce the final and official results later.
Long queues were seen outside the polling stations, DawnNews reported.
Maryam defended her father in an interview with a private television and said that Dawn Leaks report should be made public and that it was a non-issue.
Kulsoom Nawaz, who is now under treatment in a London hospital for cancer, offered thanks to the voters in a telephonic call, her daughter Maryam Nawaz said in her speech to thousands of supporters after unofficial results were announced.
While PML-N secured all its seats including NA-122, NA-137, NA-153 and NA-101 and grabbed a huge victory in local bodies elections in Punjab, clean swept in Azad Jammu & Kashmir elections and Gilgit-Baltistan polls.

Speaking from the same balcony in Model Town from which Nawaz Sharif had given his victory speech in 2013, Maryam said: "Voters have given a decision on a decision, which is that our prime minister is still Nawaz Sharif".
Insiders have said that ex-premier Sharif and his family hoped that the court might provide some breathing space to Sharif by ruling that his disqualification was not for lifetime, but only for his (third) term as premier.
PPP's candidate Faisal Mir attained 1414 votes, Milli Muslim League's supported candidate Yaqoob Sheikh received 5,822 votes and Jamat e Islami's Ziauddin Ansari received 592 votes. Mr. Saeed has lived in the open in Pakistan, despite a $10 million American bounty on his head.
Saeed is subject to a United States bounty of $10m and has been named by both the USA and UN as a "terrorist".
The election was also significant because of Muhammad Yaqub Sheikh, a U.S. designated terrorist.
For the first time in Pakistan, Biometric Voter Verification Machines are being tested. Analysts say MML is an attempt by Pakistan's powerful intelligence services to bring certain armed groups into the political mainstream to challenge the PML-N's dominance.
