The last European Elections saw PSOE – the Spanish Socialist Workers Party – win and become the largest among the progressive delegations in the S&D Group in the European Parliament. And this was not just a victory in numbers. Indeed, comrades from across the continent have been looking at Spain as a place where new politics is taking its course. To that end, the initiative “To inspire Europe: insights from the success story of social democracy in Spain” is to respond to that need for a greater understanding on the European level. It is to offer inspiration, as well as pointing out some of the most instructive lessons that can be taken away.
