Thousands of Hungarian police and firefighters protested against government plans to end early retirement, while unions disrupted traffic with a convoy of cars driving around the center of the Hungarian capital. Under the banner "Clowns' Revolution" a ballot box was set up near the parliament building, where people could "take back" votes they cast for Prime Minister Viktor Orban's conservative party Fidesz in elections last year.
