SP was an illustrated news and political magazine which was published in Spain from 1957 to 1972. The title was an abbreviation of the phrase Su Periódico (Spanish: Your Periodical).^[1] It is known for its support for Francoist rule.

SP was launched in 1957 by a group of Spanish journalists, including Rodrigo Royo^[2] and Jaime Menéndez.^[3] Its first issue appeared on 12 May that year.^[4] The magazine came out weekly,^[3] and its editor-in-chief and director was Rodrigo Royo.^[5] In September 1967 Luis Ángel de la Viuda replaced Royo as the editor-in-chief of SP and held the post until November 1968.^[2] The headquarters of the magazine was in Madrid, but it also had publishing offices in Barcelona.^[6] Due to its popularity a sister publication, Daily SP, was started in 1967 which ceased publication in 1969 due to lower popularity.^[2] SP sold 21,000 copies a week in the years 1966, 1967 and 1969.^[2] Its 1968 circulation was 24,000 copies.^[2]

In 1961 during the trial of Adolf Eichmann, a Nazi official who escaped to Argentine where he was captured, SP published an article in which the holocaust was denied.^[7] The article claimed that not Nazis but the Russians established the concentration camps for Jews in Germany.^[7] The editor-in-chief, Rodrigo Royo, also published an editorial denying the existence of the gas chambers stating that these were just the army laboratories established to test the gas masks of the soldiers.^[7]

In January 1964 SP published a controversial article about the assassination of the American President John F. Kennedy arguing that the murderers were the Dallas police.^[6] A CIA document created upon this article on 14 May 1964 stated that the magazine was a Falange supporter and that it might have links with the Italian far right publication Secolo XX.^[6] In the same document it was also speculated that this article was part of the Franco government's attempts to rebuild diplomatic relations with Mexico.^[6]

SP folded in 1972.^[2]
