Prime Minister Pedro Sanchez called a surprise snap election after the left took a drubbing in local elections in May.
In the present scenario, Sanchez' PSOE would rely heavily on Catalan separatist parties Junts and ERC or Basque separatists EH Bildu.
In 2019, two more elections were held before the PSOE and far-left Podemos agreed to form Spain's first coalition government.
