ISLAMABAD (APP) - President Asif Ali Zardari has said that the best way to pay tribute to Shaheed Mohtarma Benazir Bhutto is to defend and protect democracy and democratic institutions in the country and foil all conspiracies against it.

"Let us on this day rededicate ourselves to the democratic mission of Shaheed Mohtarma Benazir whose life was dedicated to fighting dictatorship and those seeking to defame and dismantle democratic institutions," the President said in his message on the eve of the 4th death anniversary of Benazir Bhutto being observed today.

The president urged all the democratic forces and the patriotic Pakistanis to foil all conspiracies against democracy and democratic institutions.

"While we pay tribute to her courage and leadership we also reiterate our resolve to continue fight for the values she upheld and laid down her life for," the president said.

President said her assassination was a conspiracy to rid the world of its best weapon to combat international violent extremism. It was a conspiracy to rob Pakistan of its best hope to establish a fully functional democracy, he added.

He said that government is determined to expose and punish in accordance with the law, the conspirators and perpetrators of the crime and they cannot and will not go unpunished.

The President emphasized that those who assassinated her may have succeeded in eliminating her physically but the ideas and ideals of Shaheed Mohtarma Benazir Bhutto shall never be killed.

"Let there be no doubt or mistake about it," the President said and added "May the soul of Shaheed Mohtarma Benazir Bhutto and that of all martyrs who laid down their lives for the cause, rest in eternal peace."

Meanwhile, Prime Minister Syed Yousuf Raza Gilani in his message said that Shaheed Mohtarma Benazir Bhutto was a living embodiment of courage and determination who continued to serve as a shining example of struggle against oppression and injustice.

Gilani said she was firm in her resolve and had full faith in the people of Pakistan.

The prime minister said December 27 revives the scars caused by a gruesome incident in the country's history when Pakistan was deprived of a leader of international stature.

Following the footprints of her illustrious father Shaheed Zulifqar Ali Bhutto and as an inheritor of his legacy, Mohtarma joined politics for restoration and strengthening of democracy in the country, the prime minister said.

He said Benazir was a brave woman who regarded the restoration and protection of people's rights as her foremost responsibility despite dangers posed to her life, adding that she devoted her energies, God-given qualities of head and heart and even her life for the cause of the people.

The prime minister said history would remember Mohtarma as a statesperson, political leader of the highest order and an intellectual who made the ultimate sacrifice for safeguarding the rights of the people.

Shaheed Mohtarma, the prime minister said faced the rigorous imprisonment and exile during her worth-living life but these formidable difficulties could not sway her iron-like determination.
