A joint sitting of Congress to officially name the national leaders was brought forward by a week to May 24 after a new automated voting system produced results far quicker than the manual counting of previous elections.
Senator Benigno Aquino has a massive lead in the unofficial presidential vote count, consistent with opinion polls, and the House of Representatives probe into allegations of fraud and problems with voting machines is not expected to change that.
"We expect it to be faster than previous tallies," Arthur Defensor, a three-term congressman who was elected governor of the central province of Iloilo, said in a television interview.
In 2004, Gloria Macapagal Arroyo's victory was confirmed on June 23, just a week before her inauguration as president and the start of new terms of all elected national and local officials.
Nine senators and nine congressmen have been selected to conduct the official tally of votes from 274 provinces, cities and embassies and consulates across the world next week.
"We are looking at three weeks," Senator Miguel Zubiri, an ally of the outgoing Arroyo, told reporters, saying he would ask the election agency to explain claims of irregularities about the vote count and transmission.
"We have to look at the authenticity of the flash cards, the authenticity of the certificates of canvass. We can't easily take as gospel truth whatever we'll see in those documents."
KOALA BOY
At Friday's hearing, the chairman of the committee on suffrage and electoral reforms, Teodoro Locsin, a member of Aquino's Liberal Party, said he believed the Arroyo government was behind the initial allegations that prompted the probe.
A government spokesman said Locsin's remarks were unsubstantiated and illogical.Earlier this week, a video was released of an unidentified masked man claiming to work for the elections commission and saying votes been sold and voting machines pre-programmed.
The election commission had earlier said it has discovered discrepancies involving about 150,000 votes, not enough to have an impact on the presidential race.A messy transition or drawn-out investigation could erode the positive sentiment generated by what was seen as a relatively smooth election process and the clear victory of Aquino, who has vowed to fight corruption.
