"I'm confident that the Pakistani government will provide me with the adequate security, unlike the government at the time that sabotaged my mother's security in Pakistan," he told CNN in an interview.

The 23-year-old, who returned to Pakistan last year after studying at Oxford, said her assassination was due to a combination of extremists, and Musharraf's regime.

"Al-Qaeda issued the instructions to do it, the Taliban... carried out the actual attack, while Pervez Musharraf purposely sabotaged my mother's security when he knew there was going to be attacks, so she would be eliminated.

"He murdered my mother. I hold him responsible for the murder of my mother," he added. "He'd threatened her himself in the past. He said: 'Your security is directly linked to our relationship and our cooperation.'

"When he imposed emergency, and it was clear that he was pulling the wool over our eyes. He was not interested in returning democracy to Pakistan. And my mother started to speak out more against him, the security decreased."

Bhutto's son, , said he hopes to take a greater role in Pakistan's political life.

"I did not campaign in the last election, I went to university. I don't feel like at the moment I have the mandate to take a particularly active role," he said.

"I look forward to campaigning in the next election and playing a larger role then," he said. Asked if he hoped to be Pakistan's leader one day, he said: "I'd like to help my people in any way I can.

"It's difficult times in Pakistan and we all have to help." AFP
