Pakistan has marked the fifth anniversary of the assassination of former prime minister Benazir Bhutto, with a speech by her son Bilawal Bhutto Zardari outlining his political vision for her ruling Pakistan People's Party (PPP).
The emotional and electrifying speech launched the political career of the 24-year-old, whose father Asif Ali Zardari is the current Pakistan president.
Mr Bhutto Zardari said his mother "sacrificed her life to uphold democracy".
He spoke before a rapturous crowd of hundreds of thousands of supporters in the village of Garhi Khuda Bakhsh in Sindh province telling them they were the source of power for the PPP, and pledging to support the poor and fight extremism.
The village is the Bhuttos' ancestral hometown and site of the family mausoleum.
While Bilawal Bhutto Zardari is a few months' short of the minimum age to run as a candidate in national elections which are expected to be held in the first half of 2013, he is the party's chairman and his father co-chairman, as well as being the widower of his assassinated mother.
His lineage is widely seen as a key asset for the PPP.
Senior journalist Imtiaz Alam from the Pakistani newspaper, The News, told Radio Australia's Asia Pacific it was a significant moment.
"All television networks covered it live so his entry [into politics] will be in a very big way and it's a very emotional day as well because this is the day Benazir was killed so people will have those memories revived."
Bilalwal Bhutto Zardari referred to his family's tumultuous political history in his speech.
"Every challenge is soaked in blood, but you will be the loser," he said. "How ever many Bhuttos you kill, more Bhuttos will emerge from every house."
His mother and grandfather both served two terms as prime minister of Pakistan, and both came to violent deaths.
Mrs Bhutto was Pakistan's first (and so far only) female prime minister, elected for two terms from 1988 to 1990 and 1993 to 1996.
Since Pakistan's independence in 1947, her family has played a significant role in the country's politics.
Her father Zulfikar Ali Bhutto was also a two time prime minister, and founder of the PPP, who won by a large margin in 1977 but was accused of electoral fraud by its political opposition.
The military then seized power under army chief General Muhammad Zia-ul-haq, whose government imprisoned Mr Bhutto on charges of having ordered a political assassination three years earlier, before his execution by hanging in 1978.
Benazir Bhutto was killed in a gun and suicide bombing attack after an election rally in the headquarters of Pakistan's army in Rawalpindi in December 2007.
No one has ever been convicted of her murder.
