Workers' Front (Spain)

The Workers' Front (Spanish: Frente Obrero, FO) is a Marxist–Leninist political party in Spain, with Roberto Vaquero serving as its leader since June 2022. It was founded in October 2018 as a mass organisation by the anti-revisionist party PML (RC) and registered as a separate political party in March 2019. As of 2025, the Workers' Front took part to several national, regional, local, and European elections, winning one local seat in May 2023.

The Workers' Front's political positions include Marxism–Leninism, socialist patriotism, Spanish republicanism, Spanish nationalism, hard Euroscepticism, and social conservatism, with a Hoxahist faction. Despite rejecting the left–right political spectrum, considering the mainstream left to have abandoned the working class and joined the right-wing in supporting neoliberalism, the party is commonly described as left-wing and far-left, more in line with Communist parties in Eastern Europe. It is also considered a left-conservative party, compared to the German Sahra Wagenknecht Alliance. As a result of its conservative stances on socio-cultural issues, various critics and observers compared the Workers' Front to the far-right Vox and described it as reactionary and right-wing populist in nature, including that the party was National Bolshevik, a claim that Vaquero strongly contested.
