Today Spain elected its first left-wing coalition since the civil war in the 1930s. Already, it is under siege from the country's elite - but if it succeeds, it can improve the lives of millions.
After months of refusal, Spain's PSOE has finally agreed to a left-wing coalition with Unidas Podemos. Now the hard work of defining its programme begins.
By rejecting a left-wing coalition to placate business interests, Spain's PSOE has badly miscalculated ahead of today's election – and may hand the far-right a historic victory.
Four years ago progressive platforms won power in some of Spain's biggest cities, including Madrid and Barcelona. The international left can learn a lot from their successes – and failures.
Spain's left swept to victory in last week's election. But the risk of a centrist government shows the need to do more than just mobilise progressives against the far right.
