That was probably Volen Siderov, the founder of the first nationalist political party after the fall of communism. His "Ataka" party gained some serious momentum during 2005-2009, but is now largely defunct, with very little support, partly thanks to his inconsistent and outrightly rude behaviour. They always held rallies on the Liberation Day during those years and many Bulgarians were seeing "Ataka" as the only authentic party among all other creations of political engineering under the guidance of former state security.
