Bilawal Bhutto Zardari, chairman of the Pakistan People's Party, headed to Islamabad to announce a candidate for prime minister after first visiting his mother's grave in Karachi, the Pakistani daily Dawn reported.
Dawn said Zardari likely won't be involved in active politicking until he finishes his schooling. In the meantime, his father, Asif Ali Zardari, has assumed the leadership role.
Top party contenders for prime minister were believed to be Shah Mehmood Qureshi and Yousuf Raza Gillani.
