PML-N emerges as single largest party in Pak polls
The PML-N's two closest rivals the Pakistan People's Party and Imran Khan's Pakistan Tehrik-e-Insaf lagged far behind with 31 and 26 seats, respectively.
Earlier, trends emerging from the counting of votes had shown that the PML-N led by former premier Sharif was set to bag about 125 seats.
A total of 137 directly elected seats is needed for a simple majority and the PML-N is expected to form government at the centre with the backing of independent candidates and one or two smaller parties.
The Muttahida Qaumi Movement, which had been a key partner in the last PPP-led government, bagged 16 seats while Maulana Fazlur Rehman's Jamiat Ulema-e-Islam won 10 seats in the National Assembly.
The Jamaat-e-Islami and PML-F won three seats each while the PML-Q, formed by former military ruler Pervez Musharraf, Pashtunkhwa Milli Awami Party and National People's Party bagged two seats each.
The Awami National Party, Qaumi Watan Party-Sherpao, Awami Jamhoori Ittehad Pakistan, Musharraf's All Pakistan Muslim League, Awami Muslim League, Balochistan National Party, National Party and PML-Z won one seat each.
Independent candidates bagged 25 seats.
The Election Commission announced the results for only 250 parliamentary seats, saying results were awaited from 18 constituencies in Balochistan, Punjab and Sindh provinces and the tribal areas. .
