Jolyon Jenkins reports on one man's attempt to create a new nation - a libertarian utopia - in what he says is unclaimed land between Serbia and Croatia. He has money and supporters, and half a million people have signed up for citizenship. But it's not been easy for Vít Jedlicka, Czech politician and president of "Liberland". Since he planted his flag on these marshy 7 square kilometres on the banks of the Danube in 2015, his supporters have been arrested, fined and jailed. He himself has been barred from entering Croatia. Neither Croatia nor Serbia seem to want to claim the territory, but that doesn't mean they want a zero tax libertarian enclave with no gun laws sitting between them. Jedlicka is not deterred though. He keeps up a busy schedule of international conferences, has appointed a full cabinet, and is busy opening embassies and bestowing proto-ambassadorships around the world. Jolyon Jenkins joins him as he and his foreign minister try to get back into Croatia and visit the territory he would eventually like to call home. Producer: Jolyon Jenkins.
