The 24-year-old nominal chief of the PPP was angered by Faryal Talpur's refusal to award tickets to certain candidates in Sindh province that he had recommended, a source said.
"Last month, Bilawal had recommended the names of some 200 PPP workers and asked former Sindh Chief Minister Qaim Ali Shah to give them jobs but Talpur had intervened, causing bad blood between them," the source said.
Bilawal discussed these matters with his father and sought authority to take decisions in party matters.
But Zardari sided with his sister, who plays a key role in the PPP's affairs, the source said.
"When Zardari told him that he would be handed over the command of the party after he is groomed politically, Bilawal got upset and left for Dubai," a source said.
Matters got so heated on one occasion that a source quoted Bilawal as saying: "If I had to vote, even I wouldn't vote for the PPP."
