According to unofficial results, ruling Pakistan Muslim League (PML-N) candidate Kulsoom Nawaz won the NA-120 by-election in Lahore on Sunday.
The compilation of polling results in the NA-120 by-elections is now underway after voting ended on Sunday evening for the National Assembly seat which was left vacant by Nawaz Sharif's ouster in the Panama case verdict.
"Nawaz Sharif still lives in the heart of the people", Maryam told thousands of her party's supporters, who gathered outside the party's election office in Lahore.
Nawaz is now in London for cancer treatment.
"We accept this court order against Nawaz Sharif because we don't want political chaos", said Zafar Ullah, a leader member of the ruling party.
Kulsoom Nawaz stood in place of her husband Nawaz Sharif, who was disqualified from office in July over a corruption inquiry. Pakistan's election commission will announce the official results later this week. Sharif denies receiving the salary.
The constituencies from where PML-N won national assembly seats included NA-120, NA-68, NA-71, NA-83, NA-103, NA-129, NA-69, NA-137, NA-108, NA-19, NA-122, NA-153, NA-101, NA-267, NA-63 and NA-162.More news: All 23 victims in KL tahfiz school fire identified
Some PML-N circles believe the political environment is not conducive for Sharif's return and hence, he has been advised to stay in London for some time.
A total of 44 candidates, including those from Imran Khan's Tehreek-e-Insaf and the Hafiz Saeed-backed Milli Muslim League, were in the fray for the NA-120 seat in Lahore, said to be the stronghold of the Sharifs.
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.
"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.
Sheikh received 4,174 votes, or almost 4 percent of the total vote after being backed by a new Milli Muslim League party led by an Islamist firebrand who is the subject of a $10 million bounty offered by the United States.
PML-N's lead was reduced in part by the strong showing of Yaqoob Sheikh, who the United States in 2012 designated a terrorist.
