Pakistan's new government is likely to name its choice for prime minister when parliament reconvenes next month.
The two biggest parties to emerge after Monday's election have been weighing their choice for prime minister, after agreeing to form a coalition that analysts say could place Mr Musharraf's political future in doubt.
Officials from the Pakistan Muslim League and Pakistan People's Party say the frontrunner to be prime minister is Makhdoom Amin Fahim. Mr Fahim is the widely respected Vice President of the Pakistan People's Party.
'There is an agreement that Fahim should be the parliamentary leader and candidate for PM but the announcement is unlikely to be made public before the parliament is convened into session, most probably in the first week of March,' according to a senior PPP official.
He said that although Mr Fahim was the man most likely to be named, there was no rush to make a formal announcement and internal discussions were continuing.
Former prime minister Nawaz Sharif, whose party emerged second to the PPP in Monday's vote, and Mr Asif Ali Zardari, Ms Bhutto's widower, announced that their parties would join forces after trouncing Mr Musharraf's allies in the ballot.
They have agreed that the PPP will designate the next prime minister.
Ms Bhutto's assassination at a suicide attack during a political rally in December overshadowed the election campaign.
Mr Musharraf seized power from Mr Sharif in a 1999 coup.
