Ahmed Wali Karzai, the half-brother of Afghan president Hamid Karzai, is the chairman of the Kandahar provincial legislative council and seen as the power broker of the restive region in the south of the country.
Yet, he has faced accusations of supporting the drugs trade, taking bribes and even being on the payroll of the CIA.
Afghans unhappy with Ahmed Karzai's role have said that his influence is stoking opposition to the Afghan government.
Ahmed Karzai, who once ran a restaurant in the US city of Chigago, has said that the claims are politically motivated.
And due to his influence in the country's second biggest city, Nato is counting on his co-operation in its next big push against the Taliban, expected to take place in June.
Al Jazeera's Hoda Abdel Hamid's asked Ahmed Karzai about the personal allegations and how stability can be brought to the region.
