The Pakistan Muslim League-Nawaz (PML-N) has won 12 of the 13 national and provincial seats contested in by-elections in Punjab and Khyber Pakhtunkhwa, according to unofficial results released by the Election Commission of Pakistan (ECP) on Monday.

Polling was held on Sunday across six National Assembly constituencies — NA-18 Haripur, NA-96 Faisalabad, NA-104 Faisalabad, NA-129 Lahore, NA-143 Sahiwal and NA-185 Dera Ghazi Khan — and seven Punjab Assembly seats. The results were issued through Form 47, the overall result document prepared by each constituency's returning officer.

The only seat the ruling party did not win was the Punjab Assembly seat of PP-269 Muzaffargarh, which went to the Pakistan Peoples Party (PPP). The PPP's Iqbal Khan won that seat with 46,320 votes.

In NA-143 Sahiwal, the PML-N's Chaudhry Tufail Jutt was elected after securing 136,313 votes, according to the party. In NA-129 Lahore, the PML-N's Muhammad Noman won with 63,441 votes, while an independent candidate finished second with 29,099 votes.

In NA-96 Faisalabad, the PML-N's Mohammad Bilal Badar won with 93,009 votes, ahead of independent candidate Nawab Sher Waseer on 43,025 votes. In NA-18 Haripur, the PML-N's Babar Nawaz Khan secured 163,996 votes, defeating independent candidate Shehrnaz Omar Ayub, the wife of senior PTI leader Omar Ayub Khan, who polled 120,220 votes.

Prime Minister Shehbaz Sharif congratulated the winning candidates in a message on Monday morning. He praised Tufail Jutt and Muhammad Nauman for their convincing victories in NA-143 and NA-129, and said the results reflected public trust in the government and in the development work of Punjab Chief Minister Maryam Nawaz.

In a post on X on Monday morning, the prime minister said the streak of victories for PML-N candidates in the by-election results had continued, adding that the people had expressed their trust in the party's objectives of development, stability and public welfare. He also congratulated Sardar Mahmood Qadir Khan Leghari, who won in NA-185 Dera Ghazi Khan, and the winners in PP-87 Mianwali, PP-116 Faisalabad and PP-115.

Most of the seats had fallen vacant after lawmakers affiliated with former prime minister Imran Khan's Pakistan Tehreek-e-Insaf (PTI) were disqualified months ago following their convictions in cases linked to the violent protests of May 2023. Supporters of Khan attacked government and military installations after his brief arrest in a corruption case on 9 May 2023, leading to a nationwide crackdown. Khan and his party deny that they instigated the attacks.

The PTI has accused the government of rigging the by-elections in its favour. Omar Ayub alleged on X that the returning officer in NA-18 Haripur was entering results from fabricated Form 45s, claiming the PTI had a lead of 27,000 votes on the original forms held by the party. The ECP and the authorities have rejected rigging allegations in the past.

Strict security measures were in place on polling day as thousands of voters went to the ballot box across the two provinces.
