Political parties in the Philippines play a crucial role in the country's democratic system. They are responsible for representing various interests and ideologies, helping to organize elections, and forming the government. Major parties include the Liberal Party, Nationalist People's Coalition, and Partido Demokratiko Pilipino–Lakas ng Bayan. The political landscape is characterized by a multi-party system, where parties often form coalitions to gain a majority in the Philippine Congress. Elections are held every three years, and party affiliation can significantly influence a candidate's chances of winning, as well as their ability to implement policies.
