Benigno "NoyNoy" Aquino has been declared the official winner of the Philippine presidential election after campaigning on promises to ease poverty and fight corruption.

Tuesday's confirmation comes a month after voters went to the polls.

The son of Filipino democracy heroes, Aquino secured nearly 42 per cent of the total votes cast, making his triumph the most emphatic victory in modern Philippine history.

The country's parliament is set to officially proclaim him president-elect on Wednesday, and he will take office when outgoing president Gloria Arroyo steps down on June 30 after almost a decade in power.  

Aquino tapped into the huge well of public support for his parents, who are considered heroes for their role in ending the 20-year dictatorship of Ferdinand Marcos.

Illustrious parents

His father, Benigno "Ninoy" Aquino, was shot dead in 1983 as he returned from exile to lead the pro-democracy movement. His mother, Corazon Aquino, took over his role and led a revolution against Marcos three year later, before serving as president.

She died last year, unleashing an outpouring of support for the family that persuaded him to run for the presidency.

Aquino has vowed to boost foreign investment, rein in wasteful government spending, improve the civil service and invest in education.

He admits that it will take more a single term in office to carry out the social transformation he envisages for the Philippines.

"But we are hoping to provide that impetus and momentum to carry over into the next administration," he said after the poll last month.
