Flavia Kleiner is a political activist. She studied contemporary history, constitutional law and philosophy of law in Fribourg and Jerusalem. Her work focuses on the future of democracy, the rule of law, the current rise of populism on the right, and civil society activism. In 2014, after the so-called ‘Initiative Against Mass Immigration’ by the populist Swiss People’s Party was passed by a waferthin margin, she co-founded the liberal movement Operation Libero which managed to overturn the result. Since then, Operation Libero’s innovative and effective campaigning has successfully defeated the nationalist conservative agenda of the Swiss People’s Party in several referenda. In November 2018, her letter on how to counter right-wing populism was published in The Guardian.
