Key facts on Philippine elections

Below are key facts and figures on the Philippines and its political system:

-- The Philippines became an independent nation in 1946, following more than 400 years as a colony of either Spain or the United States. National languages are Filipino and English.

-- Its system of government is a US-style democracy with a president, a bicameral legislature and an independent judiciary. A president is limited by the constitution to a single term of six years. Presidents and vice presidents are elected separately. A new constitution was written after a "People Power" revolution ousted dictator Ferdinand Marcos in 1986.

People and poverty

-- The country is run by remarkably few political families. A study released in April showed 70 percent of members of Congress belonged to a political dynasty.

-- Political activists and analysts say elite rule and celebrity politics are set to be deeply entrenched in these elections. They cite as an example the likely dominance of powerful politicians' relatives of the 12 available Senate seats. Boxing hero Manny Pacquaio is also likely to win a Senate seat.
