THE GUARDIAN WEEKLY: The latest issue features ‘KEEP LEFT’ – How Lula won a historic fourth term; Serbia celebrates defeat of Vučić; Competitive yoga – A stretch too far?

How many grinning faces, jubilant crowds and celebrating politicians can you fit into a single issue of the Guardian Weekly? That’s not a question that often troubles us, but the spectacular triumph of President Luiz Inácio Lula da Silva, winning a historic second-round vote after losing the first to rightwing opponent Flávio Bolsonaro, and the victory of the student-led campaign against autocrat Aleksandar Vučić in Serbia gave me a happy problem to solve this week. In an era when the right seems to be riding high in the world, popular pushbacks against strongmen politicians is something to celebrate.

For our Brazil cover story, Tom Phillips and Tiago Rogero report on the reaction to Lula’s victory and how he pulled eventual success from the jaws of what, until the first results came on Sunday evening, seemed a probable defeat. As government health minister Alexandre Padilha said that evening: “It’s a massive victory – not just for Brazil. It’s also an important signal to the rest of Latin America and to the world.” But, as commentator Jordana Timerman cautions, Brazil has been an exception in Latin America in successfully resisting Donald Trump’s attempt to achieve hegemony over the region.
