Later in the decade, Fraga established himself as one of the more prominent members of a reformist faction in the government who favoured opening up the government from above. He introduced an "a posteriori" censorship law, which was based on lifting pre-publication censorship and a reduction in its strictness. Additionally, a certain sexual liberality in films was popularly summarized in the expression "Con Fraga hasta la braga" ("With Fraga can see even the panties"). His departure from the government was prompted by the MATESA affair: the debt of the important publisher Manuel Salvat Dalmau was tangled with members of the Opus Dei, faction which Fraga opposed. When he published this information, the caudillo Franco expelled both sectors.
