N leader Maryam Nawaz leaves Lahore for London

Justice has been served: Imran on SC verdict

According to information, the PML-N leader will congratulate her mother Kulsoom Nawaz on her victory in the NA-120 by-poll and will also apprise her about the election campaign that she led in the constituency on her behalf.

Meanwhile, Nawaz picked Maryum to lead her mother's election campaign, depriving his nephew, Hamza Shahbaz, from the job.

Kulsoom is in London where she is undergoing treatment for her throat cancer.

Knowing the delicacy of the power struggle, Nawaz, after his ouster, had announced his younger brother to be his successor but to be a PM, Shahbaz had to be elected to the National Assembly.

The country's Supreme Court, which has been hearing a high-profile corruption case against Nawaz Sharif and his children, ruled in July that Sharif had concealed overseas assets, and ordered his removal from office for "dishonesty".

Her rival candidate, Dr. Yasmin Rashid from Tehrik-e-Insaf (PTI) of Pakistan's former cricket star Imran Khan, obtained more than 46,000 votes, local Dunya TV reported, quoting unofficial results.

Some voters complained that the process inside the polling stations was taking too long and that some of the polling stations were without electricity.

"It's very hard for them to take this from us", said Sohail Butt, 48, a PML-N voter in the Mozang area of the city. Fewer votes for the PML-N would allow political opponents to claim that even on the Sharif family's home turf the corruption allegations are having an effect. She did inform about holding of Iqama but did not mention the earning through it and details of bank accounts, they said.

Faisal Mir, the candidate of the main opposition Pakistan Peoples Party, got only 1,414 votes raising questions about the party's position in Punjab province.

"I am satisfied by the polling, particularly the presence of army at the polling stations", Rashid said after visiting a polling station for women in the electorate located within Lahore, Pakistan's second-largest city.
