Nawaz Sharif, daughter board flight to Lahore

Maryam Nawaz tweeted a video message from her father after they stopped in Abu Dhabi before they travel on to Lahore.

They have been been convicted in the Avenfield corruption case.

Their flight, Etihad Airways flight EY243, landed at Lahore's Allama Iqbal International Airport at around 9:15 pm.

They are expected to be airlifted in two helicopters from Lahore to Adiala jail in Rawalpindi. Deputy Inspector General Operations Shahzad Akbar said 10,000 police officers will be deployed across Lahore on Friday to "maintain law and order".

Underscoring the tensions gripping Pakistan in the run-up to the poll, a suicide bomber had killed more than 100 people at an election rally a few hours earlier, in the deadliest such attack in the country in more than three years.

The National Accountability Bureau has arranged two helicopters for shifting former prime minister Nawaz Sharif and his daughter Maryam Nawaz to Islamabad after arresting them upon their entry into Pakistan, reported Geo News.

Meanwhile, there are reports of clashes between supporters of Sharif and police in Lahore and several other cities.

The PML-N supremo further said he would render the sacrifice for the future generations of the country.

Sharif, who was in London with his wife and children when the verdict was announced, said he is returning to Pakistan from London to fulfil his pledge to "honour the vote".

They are set to be arrested after their arrival here from London following their conviction in a corruption case described by Pakistan's embattled former prime minister as a "blind revenge" amid a crackdown on his party activists.

A Pakistani accountability court on Friday sentenced Sharif in absentia to 10 years in prison for corrupt practices linked to his family's purchase of upscale London flats.

Urging the Election Commission of Pakistan (ECP) to take notice of the emerging situation, the PML-N president said, "By the time our workers are released polls will be over".

Additionally, Captain (retd) Safdar, Sharif's son-in-law, was given a one-year sentence without any fine.

The letter, according to sources, read that a rally will be held in Lahore upon the former premier's arrival that is likely to create challenges in arresting the father-daughter duo, who are now in London to tend to Sharif's ailing wife, Begum Kulsoom Nawaz.
