The Koalisyon ng Nagkakaisang Pilipino (Coalition of United Filipinos), or KNP, is the coalition of the dominant opposition. Its standard bearers were Fernando Poe, Jr. (died Dec. 14, 2004) for president and Sen. Loren Legarda-Leviste for vice-president. The leading party of this coalition is the Angara wing of the Laban ng Demokratikong Pilipino (Struggle of Democratic Filipinos) or LDP. The LDP split in late 2003 over issues on who is to be their standard bearer. Most of the party followed the lead of the president, Sen. Edgardo Angara especially with the support of the former president Joseph Estrada and former first lady Imelda Marcos. The other major party under this coalition is Estrada's Partido ñg Masang Pilipino (PMP; Party of the Philippine Masses).
