The election was held as provided under article 99.5 of the Spanish Constitution, as a result of the failure in government formation negotiations between the Spanish Socialist Workers' Party (PSOE) and Unidas Podemos following Pedro Sánchez's failed investiture voting on 23–25 July 2019. On 17 September 2019, King Felipe VI declined to propose any candidate for investiture ahead of the 23 September deadline as a result of the lack of agreement between parties, with a new general election scheduled for 10 November. The failure in negotiations prompted Podemos founder Íñigo Errejón to turn his regional Más Madrid platform—which had obtained a remarkable result in the 26 May Madrilenian regional election—into a national alliance under the newly-created brand of Más País, comprising a number of regional parties and former Podemos and United Left (IU) allies, such as Coalició Compromís, Equo or Chunta Aragonesista (CHA), while also seeing an exodus of a number of Podemos officials into Errejón's new party.
