PML-N President Shehbaz Sharif was elected as the 23rd Prime Minister of Pakistan after 174 lawmakers voted in his favour as Pakistan Tehreek-i-Insaf MNAs boycotted the election.

Earlier, PTI MNAs had walked out of the halls, with Shah Mahmood Qureshi - who was the party's candidate for the top slot - announcing that they would be resigning masse from the NA, according to Dawn.

PML-N's Ayaz Sadiq presided over the session after Deputy Speaker Qasim Suri his conscience did not allow him to conduct the session.

Announcing the results, Sadiq reminisced that he had also chaired a session during which PML-N supremo and Shehbaz's elder brother was elected as the premier.

"And today, I have the honour of chairing the session for Shehbaz Sharif's election," he said.

"Mian Mohammad Shehbaz Sharif has secured 174 votes," he announced. "Mian Mohammad Shehbaz Sharif has been ... elected as the prime minister of the Islamic Republic of Pakistan."

As soon as Sadiq announced the result and said Shehbaz was the new prime minister of Pakistan, lawmakers began shouting slogans in favour of Shehbaz and Nawaz.

The speaker asked Shehbaz to move to the seat of the prime minister in the house and he shifted to the treasury benches amid cheers, with other members of the former joint opposition following suit.

In his maiden address to the house as the prime minister, Shehbaz he thanked Allah for "saving Pakistan".

He said it was the first time in Pakistan's history that a no-confidence motion against a prime minister had been successful. "And good has prevailed over evil."

Shehbaz today was a big day for the entire nation when a "selected" prime minister was sent packing in a legal and constitutional manner.

He added that the US dollar's value declining by Rs8 signified the "happiness of the people".

The development comes two days after an unceremonious end to Pakistan Tehreek-i-Insaf (PTI) chief Imran Khan's tenure as the country's chief executive through a no-confidence vote.

After taking the chair of the speaker, Sadiq read out the rules and procedure for the election of the prime minister and asked for the bells to rung for five minutes so that all lawmakers could come inside the halls before the voting began.

He said after the bells stopped ringing, the assembly's entrances and exits would be locked and would remain so until the voting concluded.

Thereafter, Sadiq read out the names of the contenders, PML-N President Shehbaz Sharif and PTI's Shah Mahmood Qureshi. In a slip of tongue, he named PML-N supremo Nawaz Sharif as one of the contenders initially and quickly corrected himself, clarifying that he meant to say Shehbaz.

"I apologise Shehbaz sahab, Nawaz's name remains in my heart."

Sadiq then asked the lawmakers supporting Shehbaz to proceed to lobbies on his left side for voting. Similarly, he asked those who wanted to vote in favour of Qureshi to proceed to the lobby on his right side to cast their votes.

The voting has ended and the result sheet has reached the NA secretary who is counting the votes.

The NA session for the election of the prime minister today began with the recitation of the Holy Quran.

After the recitation, Deputy Speaker Qasim Suri, who was initially chairing the session, explained his rationale behind his contentious ruling to dismiss the no-confidence motion against erstwhile prime minister Imran Khan on April 3.

"The ruling was declared unconstitutional by the court ... and we all are obliged to respect the court. But I want to tell you the reason behind my ruling," he said, adding that he had taken the decision "as a responsible Pakistani and deputy speaker of the NA".

He then referred to a communique, which purportedly contained evidence of a foreign conspiracy to topple Imran Khan's government, saying that cable was discussed in the federal cabinet, a meeting of the National Security Committee and a meeting of the parliamentary committee for security.

"And it was proven that the no-confidence motion [was linked] to a foreign conspiracy," he said.

Suri added that on April 9, it was decided during a cabinet meeting that the cable would be declassified and sent to then-NA speaker Asad Qaiser by the government.

"Asad Qaiser read and reviewed it [the cable]," he said. He then held up a piece of paper, saying that he had the cable with him. In the letter, he continued, an "open threat" had been made to Pakistan.

He added that the communique was sent to Pakistan before the no-confidence motion was submitted on March 8.

The cable, he continued, stated that in case of the failure of the no-confidence motion, Pakistan would have to face dire consequences.

The deputy speaker went on to question, "Was talking about an independent foreign policy, independent economy ... and fighting the case of Islamophobia Imran Khan's fault?"

"Was he punished because he refused slavery?"

The deputy speaker announced that he was sealing the cable and sending it to Chief Justice of Pakistan Umar Ata Bandial.

Before giving the floor to PTI's Shah Mahmood Qureshi, he said his April 3 was in line with the oath he had taken as the deputy speaker and the Constitution. "I did it to stop a regime change at the will of another country," he said.

But, he added, "I accept the Supreme Court's decision on the matter."

He appealed to MNAs to think about the matter and apologised for hurting anyone's sentiments.

Qureshi began his speech by noting that a constitutional process would reach its conclusion today.

"An election will be held, in which one side will be successful and another will be freed," he said. "Today, the nation is at a crossroads. It has to choose between the path of independence and the path of slavery."

He then thanked Imran Khan and his party for showing confidence in him and nominating as the candidate for the prime minister's slot.

Qureshi continued that today, there was a cohort driven by a single ideology on one side and a coalition of parties, which was "unnatural" in the PTI's view, on the other.

PML-N President Shehbaz Sharif - who is the former joint opposition's candidate for the prime minister's slot - and PTI's Shah Mahmood Qureshi were in the race to become the country's new prime minister.

However, after the PTI boycotted the elections and walked out of the assembly, Shehbaz is the lone contender for the prime minister's slot and will be elected unopposed.

According to the NA agenda issued by the house's secretariat for today, the session for the prime minister's election will begin at 2pm.

The premier's election is the only item on the agenda - apart from the recitation of the Holy Quran and a Naat, which marks the commencement of every NA session - stating that the house would convene to vote for the new leader of the house "as required by Article 91 of the Constitution of the Islamic Republic of Pakistan, read with rule 32 of the Rules of Procedure and Conduct of Business in the National Assembly, 2007".

Former prime minister Imran Khan arrived at Parliament House ahead of the session for the election of a new premier to chair a meeting of the party's parliamentary committee.

When asked to comment on protests held across the country by PTI supporters last night, he smiled and said: "God is the one who gives respect."

Submission of nomination papers

Both Shehbaz and Qureshi had filed their nomination papers yesterday, hours after Imran Khan's ouster as the prime minister.

Qureshi had submitted four forms with the NA Secretariat, while Shehbaz had filed 13 forms.

During the submission of the nomination papers, the PTI had raised objections to Shehbaz's nomination and subsequently PTI's Qureshi and Babar Awan had exchanged heated words with PML-N leaders Zahid Hamid and Atta Tarar.

The senior PTI leaders had submitted objections against Shehbaz, stating that the latter was contesting the election on the day of his expected indictment in a money laundering case. They were of the opinion that he did not deserve to be the new PM due to his "involvement" in corruption cases.

On Monday, the court, however, deferred the indictment.

Responding to these allegations, Tarar had said since Shehbaz had not been convicted in any case, his nomination could not be rejected merely on the basis of allegations. Hamid had reminded the PTI leaders that nomination could be rejected only on the grounds mentioned in the Constitution and Rules of Procedure and Conduct of Business in the NA, 2007, under which the candidate for the office of PM must be a Muslim, an MNA and signature of the candidate and his proposer and seconder must be genuine.

The NA secretary had eventually accepted the nomination papers of both the candidates.

No-trust motion ousts Imran

The election for the prime minister comes two days after a premature end to the PTI tenure following weeks of political turmoil.

The saga began with the joint opposition - primarily the Pakistan Democratic Movement (PDM) and the PPP - submitting the no-confidence motion against Imran Khan with the NA Secretariat on March 8.

In the days to follow, the country's political landscape was abuzz with activity as parties and individuals changed alliances and the PTI and opposition were seen trading barbs and allegations alongside intensifying efforts to ensure their success in the no-confidence contest.

Eventually, major allies of the ruling PTI - Balochistan Awami Party and Muttahida Qaumi Movement-Pakistan - deserted the government and joined the opposition ranks which led to PM Imran losing his majority in the lower house of parliament.

In addition, over a dozen PTI dissident MNAs have already come into the open with their criticism on PTI policies.

For its part, the PTI had managed to secure the support of another one of its key allies, the Pakistan Muslim League-Quaid (PML-Q), as Usman Buzdar stepped down as the Punjab chief minister in favour of the PML-Q's Chaudhry Pervaiz Elahi, who the ruling party announced as its candidate for the province's new chief executive.

However, one of the many twists in the saga emerged when Imran Khan claimed to have evidence of a "foreign conspiracy" to oust his government. At the PTI's rally on March 27, the premier had pulled out a piece of paper from his pocket and waved it at the crowd, claiming it was evidence of an "international conspiracy" being hatched to topple his government.

The PTI accused the opposition of being part of the foreign plot and tried to turn the tide in its favour by disclosing some of the details in the "threat letter" to journalists and lawmakers.

Separately, after a few delays, the National Assembly finally convened on April 3 to vote on the no-trust motion against the premier.

However, the PTI would prove to be five steps ahead of the opposition as the deputy speaker, who was chairing the session, dismissed the motion, saying it was part of a foreign conspiracy to oust Imran Khan, after Chaudhry spoke on a point of order, citing Article 5 of the Constitution, which mandates loyalty to the state for every citizen.

Within minutes of the pandemonium that broke out, Imran Khan appeared on television to announce that he had advised the president to dissolve the lower house of parliament and called on the people to prepare for fresh elections.

The government's move also led to the Supreme Court taking suo motu notice of the deputy speaker's ruling with Chief Justice of Pakistan Umar Ata Bandial stating that all orders and actions initiated by the prime minister and president regarding the dissolution of the NA would be subject to the court's order. Meanwhile, opposition parties also filed pleas questioning the legality of Suri's ruling.

What followed were five days of marathon hearings where the court heard arguments from the government and the opposition. At the same time, the PTI began its preparations for the next elections, insisting on the existence of a foreign conspiracy behind the no-confidence motion.

On Thursday last week, the apex court - in a historic ruling - set aside Suri's ruling and the subsequent dissolution of the assembly by the president on the erstwhile PM's advice, with all five judges unanimously voting 5-0 against it.

The court's verdict also restored the prime minister and his cabinet in their position and directed for the session of the National Assembly to reconvene on Saturday no later than 10:30am, saying that the session cannot be prorogued without the conclusion of the no-trust motion against Imran.

On Saturday, the session commenced at 10:30am but continued into the wee hours of Sunday as the opposition's clamour for immediate voting throughout the day fell on deaf ears amid lengthy speeches delivered from treasury members on the floor of the house. The session was adjourned four times and the voting took place only after Asad Qaiser resigned at the speaker of the house almost 15 minutes before midnight, which according to legal experts, was the deadline to implement the Supreme Court's orders to conduct voting on the no-trust motion.

PML-N's Ayaz Sadiq, who was among the panel of chairmen, had then chaired the session, with the voting on the motion finally taking place at 11:58pm.

The results were announced in the early hours of Sunday, with 174 MNAs voting in favour of the resolution, two more than the required number of 172 out of a total 342 for the resolution to pass.

History was written as Imran Khan became the first prime minister in Pakistan to have been removed from office through a no-confidence vote.
