MANILA, Philippines -- Former President Joseph Estrada will make his "comeback" trail to Malacañang official on Monday as he and his running mate, Makati Mayor Jejomar Binay, file their certificates of candidacy on Bonifacio Day.

Estrada and Binay, who will be joined by the United Opposition's (UNO) senatorial candidates, vowed to return power to the masses as they offered the executive experience needed to rebuild the country.

"President Estrada and I possess the experience and capability to respond to crisis. We do not evade responsibility. We do not keep quiet, and we do not leave the country in times of crisis and difficulties," said Binay in a statement.

"We know and we are ready to address the needs of the people for a new leadership that is competent, capable and cares for the poor," he said.

Estrada was elected mayor of San Juan, senator, vice president, before he won by a wide margin as president in 1998. He was ousted from office in a civilian-led military-backed revolt on charges of corruption in 2001.

Binay, meanwhile, served as mayor of the country's financial district for more than 20 years, initiating wide-ranging social services for the city’s poor in the area of education and health.

Before the filing, Estrada will unveil UNO's platform of government during the 9 a.m. program at the Liwasang Bonifacio in Manila.

A manifesto of support for the Erap-Binay tandem will also be read by Ronald Lumbao of the People's Movement Against Poverty.

The party will then march to the Commission on Elections via Taft Avenue and Intramuros, to file their CoCs.

Binay said the challenges of rebuilding a country mismanaged for eight years and weighed down by corruption at the highest level of government would require leaders with executive experience and real concern for the poor.

"The urgent task of lifting the people from poverty and hunger, making government work for the people and ending corruption should not be entrusted to untested leaders who are not sincere in helping the poor," he said.

He said Estrada's pro-poor programs were derailed when he was forcibly removed from power in 2001.

"We will now have the opportunity to return power to the masses and to continue President Estrada' s programs that will uplift the conditions of the poor," said Binay.
