The 10 November Spanish elections have left a more unstable situation than the 28 April elections. Although the right has been defeated again, the PSOE leadership failed in its political calculation that it would emerge strengthened, and the tactics of the UP leadership – to ruin Sanchez's investiture and risk new elections – were also an error that lost them votes and seats. Political polarisation, agitated by the Catalan national question, is reflected in the strengthening of the extreme right, of Catalan independence parties, and Basque and Galician nationalism.
