In the disruption caused by the Second World War, two delegates represented the province of Cebu (of which the municipality of Opon was a part) in the National Assembly of the Japanese-sponsored Second Philippine Republic: one was the provincial governor (an ex officio member), while the other was elected through a provincial assembly of KALIBAPI members during the Japanese occupation of the Philippines. Upon the restoration of the Philippine Commonwealth in 1945, the province's seven-district configuration was restored. The Municipality of Opon, converted into the city of Lapu-Lapu in 1961, remained a part of Cebu's second district until 1972.
Two years after Lapu-Lapu was converted into a highly urbanized city in 2007, it was also granted separate congressional representation by virtue of Republic Act No. 9726, approved on October 22, 2009. The law separated the city from Cebu's sixth district to form its own congressional district[2] after the 2010 elections.
