Senator Juan Miguel Zubiri shocked the Senate by his resignation.
Zubiri said he could no longer take the accusation against him.
The Senator stepped down before the Senate Electoral Tribunal announced their decision, in connection with the protest
of Aquilino Pimentel III.
He said that his family is already hurt by personal attacks.
Zubiri disclosed that he was not involved in any form of cheating but he was a victim of so called election syndicates.
