The party of the assassinated Pakistani opposition leader, Benazir Bhutto, meets on Sunday to discuss a successor and whether to take part in January's election.
Members of the Pakistan People's Party (PPP) have gathered at Ms Bhutto's family home in Larkana to hear her political will, which could name her choice for a leader, BBC reported.
Bhutto's husband, Asif Ali Zardari, is a possible successor, according to correspondents.
"It depends on the party and it depends on the will," Zardari told BBC after asked whether he wanted to lead the PPP.
The party is also to decide whether to follow the example of opposition leader Nawaz Sharif, a long-time Bhutto rival, who said his party would boycott the elections, demanding President Musharraf's resignation.
Meanwhile, the Pakistani president ordered firm action to crack down on unrest following Ms Bhutto's death with PPP supporters believing he is responsible for the assassination.
The PPP has been a leading voice for the restoration of democracy since Musharraf's military coup in 1999.
