A crowd of people moves in unison through the long corridors of Hall 8 of the Barcelona Fair as if following a rock star. No one this Friday has generated the expectation of José Luis Rodríguez Zapatero, the great protagonist of the first day of the Global Progressive Mobilisation (GPM). "Progressivism must be united, it must be brave. We will never win by complaining about what the right does, but by convincing with our values and convictions," stressed the former Spanish president just before starting to attend to his followers. Some of them, young enough not to remember him in Moncloa, asked him to make the eyebrow gesture that he exploited so much during his campaign, and he gladly granted it.
