MANILA, Philippines -- Former president Joseph Estrada has announced his decision to run again "if the opposition would not unite."

Estrada made this declaration in a television interview Wednesday when asked whether he would run in 2010, saying this will be his "last option."

"If the opposition does not unite, I will run. That?s my last option. If they don?t unite, I will run," said Estrada who was ousted in a popular revolt in 2001 and replaced by his then vice president Gloria Macapagal-Arroyo.
