Former Interior Secretary Mar Roxas, the administration bet in next year's Philippine presidential race, has registered his candidacy as election fever heats up in one of Asia's most rambunctious democracies.

President Benigno Aquino III heard mass with Roxas and his running mate Rep. Leni Roberedo, and family members at the Manila Cathedral Thursday before they filed to run at the Commission on Elections office across the church. Roxas and Robredo are running under Aquino's Liberal Party.

The elections commission says 60 people have registered to run for president and 13 for vice president so far. But the commission says most are unknown, add those determined in an evaluation to be "nuisance candidates" who cannot mount a national campaign will be stricken from the candidate's list.

The election is in May.
