BILAWAL BHUTTO ZARDARI (PAKISTAN PEOPLE'S PARTY): Bilawal, 29, is the son of the slain former PM Benazir Bhutto and his party's strength lies in southern Sindh province. Since his mother's assassination by Taliban militants in 2007, the party's fortunes have dwindled. The Bhutto family has been dogged by tragedy. The party's founder, Zulfikar Ali Bhutto was ousted in a military coup and hanged by dictator Gen. Ziaul Haq. Both his sons were killed by unknown assailants. Benazir Bhutto's only surviving sibling, her sister Sanam, lives in Britain and has stayed out of politics. Benazir's husband, Asif Ali Zardari, served as Pakistan's president for five years until 2013. He is seeking a seat in parliament in Wednesday's elections. Bilawal has tried to revive the party's dwindled popularity by leading rallies despite election-related violence but analysts do not believe he can win a simple majority. (Photo | AP)
