A parliamentary election was held in the Philippines on April 7, 1978 for the election of the 165 regional representatives to the Interim Batasang Pambansa (the nation's first parliament). The elections were participated in by the leading opposition party, the Lakas ng Bayan (LABAN), which had twenty-one candidates for the Metro Manila area while the leading candidate was the jailed opposition leader Ninoy Aquino, and the Marcos regime's party known as the Kilusang Bagong Lipunan (KBL), which was led by the then-First Lady Imelda Marcos. Ninoy was allowed to run by his fellow partymates under the Liberal Party, who boycotted the election and was not allowed to campaign, and so his family campaigned for him. The night before the election on April 6, 1978, a noise barrage was organized by the supporters of (LABAN) which occurred up to dawn.
