In May 2018, national PSOE leader Pedro Sánchez filed a vote of no confidence in the government of Mariano Rajoy that placed him as Prime Minister of Spain with the support of Podemos and Catalan and Basque nationalist parties. Citizens, Diaz's partner in Andalusia and being a party which strongly opposes these movements, withdrew their support to PSOE and Díaz, triggering a snap election. In the 2018 Andalusian regional election support for Diaz's socialist party dropped to 33 seats, losing 14 from the previous election. Once again her political party was the most voted in Andalusia, but Susana Diaz could lose presidency of Andalusia if the People's Party and Citizens join forces with VOX; a new political party without previous representation that retrieved 12 seats and was labelled by Diaz as "far-right".
