After the assassination of Obregón, who was recently elected, in 1928 the party's power started to decline. Morones was suspected to benefit from Obregón's death and lost support. In 1929, Calles founded the National Revolutionary Party (PNR), which became the new ruling party and absorbed much of the cadres and leadership of the PL. No longer endorsed by the Mexican political elite, the Laborist Party fell into irrelevance. It last participated in the election in 1940, when it supported the centre-right candidate Juan Andreu, and disappeared entirely soon after.
