Thousands came out to cheer the swearing in of new mayors in Spain on Saturday June 13, in scenes not seen since 1979 or perhaps 1931. The May 24 municipal and regional elections represented a serious setback for the ruling right wing PP. But the extent of their defeat was not clearly visualised until June 13, when mayors representing parties and alliances to the left of social democracy were sworn in, in 4 of the 5 largest cities in the country: Madrid, Barcelona, Zaragoza and Valencia. The fifth, Seville, was taken over by a PSOE mayor, with the support of Podemos-backed “Participa Sevilla”, and United Left (IU).
