Greece's far-left former finance minister Yanis Varoufakis called Sunday on the next leader of Spain to defy the European Union, speaking to hundreds of cheering onlookers during an anti-austerity gathering in Madrid. The so-called "Plan B" weekend event near the grounds of Madrid's former abattoirs — now converted into a sprawling cultural centre — saw activists, actors and left-wing politicians from Spain, France, Britain and other countries get together as a pan-European movement against EU-imposed austerity gathers pace. It comes at a time of uncertainty for Spain where December elections produced a hung parliament, as voters fed up with years of crisis-sparked austerity snubbed the traditional conservative and socialist parties and flocked to two new groupings — centre-right Ciudadanos and far-left Podemos.
