Aquino, son of democracy icons who fought the late dictator Ferdinand Marcos, will take his oath as the country's 15th president on Wednesday.

More than 1,000 police officers have been deployed to secure his inauguration at Manila's seaside Rizal Park, which was designated a no-fly zone. Military forces in the capital also have been placed on full security alert for the inauguration.

In a news conference on Tuesday, Aquino introduced his Cabinet, which included loyal supporters and former Cabinet members of outgoing leader Gloria Macapagal Arroyo who broke off from her government when she faced vote rigging allegations in 2005.

He named as his Defense Secretary retired Gen. Voltaire Gazmin, who headed the elite force that secured his mother, the late President Corazon Aquino. Gazmin defended his mother's government against at least seven coup attempts.

Aquino said he will immediately form a "Truth Commission" to be headed by retired Chief Justice Hilarion Davide to investigate allegations of graft against and other corruption scandals as well as human rights violations under Arroyo's turbulent nine-year rule.

Officials who committed "crimes against the people will be made to pay," Aquino said. "I want a solution that will stand up to the scrutiny of a court trial." Teresita Deles, who was named Aquino's peace adviser, said she will form separate negotiating panels to pave the way for the resumption of peace talks with communist and Muslim guerrillas.

"It is very clear that peace will not be made just on the table. There has to be development, there has to be good governance," Deles said.

Arroyo, who survived four coup attempts and opposition impeachment bids over allegations of corruption, vote fraud and human rights abuses, will move on to the House of Representatives where she won a seat in the May 10 election. She has denied any wrongdoing.
