Who benefited the most by the ination of Benazir Bhutto? Musharraf? her husband Asif Zardari? who?

BB's political rivals, the Q League has been accused by her husband of being the killer league. They too did not like her getting in their way of another term. But they are not likely to gain from her elimination. It can be her right hand man in the party, Amin Fahim, who had no chance of becoming prime minister in her presence. Mushy baby also would love to see a vegetable, and not the Iron Lady running the govt. So who was the principal beneficiary of this murder? (I would prefer only those answer, who understand Pakistani politics.)
