 Thus began, for Haya and his supporters, the stage of "the great clandestinity", which would only conclude, officially, in 1945 (to increase again between 1948 and 1956, under Manuel A. Odría administration).In the 1936 presidential elections, the Peruvian Aprista Party supported Luis Antonio Eguiguren, who attained the highest number of votes; however, Congress invalidated the election on the grounds that the votes in favor of Eguiguren came from members of an outlawed party, an unheard-of argument, even more so considering that suffrage was secret.In 1945, the Peruvian Aprista Party returned to legality by participating in the coalition of the National Democratic Front (FDN).
