A look at the seats up for grabs in Pakistan's elections

ISLAMABAD — Pakistanis go to the polls Wednesday to elect a third straight civilian government, with more than 12,000 candidates vying for 272 seats in parliament and 577 seats in four provincial assemblies.

Under Pakistani law, separate seats are reserved for women and non-Muslim minorities, which comprise about 4 percent of the country's more than 200 million residents.

The election comes amid controversy surrounding former Prime Minister Nawaz Sharif, who recently returned to the country from England to face corruption charges even as he has sought to return his party, the Pakistan Muslim League, to power. Meanwhile, popular former cricket player Imran Khan hopes to become the next premier.

Here is a look at contested seats in the National Assembly and four provincial assemblies and the number of candidates running.

NATIONAL ASSEMBLY

The National Assembly in the capital Islamabad is comprised of 342 seats, of which 272 open seats are being contested. The remaining 70 seats are reserved for women and non-Muslims, with 60 for women and 10 for non-Muslims.

Punjab is the largest province and key to the formation of a new government with 141 assembly seats being sought by 1,623 candidates. For the 35 seats reserved for women from Punjab, 73 candidates are listed.

The party obtaining the majority of seats in Punjab will likely form the next government. The three major parties — Khan's Tehrik-e-Insaf, the former ruling Pakistan Muslim League and Bilawal Zardari's Pakistan People's Party — are focusing on Punjab. Khan, Zardari and PML-N chief Shahbaz Sharif are campaigning for multiple seats. (Pakistani law allows candidates to run for multiple seats).

In southern Sindh province, there are 61 National Assembly seats being contested by 824 candidates and 48 candidates are vying for the 14 seats designated for women.

For northwestern Khyber Pakhtunkhwa province, where there are 39 National Assembly seats, there are 725 candidates in the field. There are eight reserved seats for women with 35 candidates listed.

In southwestern Baluchistan province, 16 seats are up for grabs with 287 candidates running for them, and three seats for women with 16 candidates.

The capital city Islamabad has three assembly seats and this year 73 candidates are in the running.
