(ANSA) - BELGRADE, AUG 17 - Alpac Capital, a Portuguese financial investment firm, has acquired four of Serbia's leading independent (and opposition) media outlets. Its CEO, Pedro Vargas David, who is rumoured to have ties to some European right-wing groups and Viktor Orbán, took over as editor-in-chief today, dismissing the previous editors and raising concerns among their respective editorial staffs and opposition. The news, which has so far gone unreported by pro-government media, was released today primarily by the affected outlets: N1, Nova (including its portal), Danas, and Radar, which were previously part of the Adria News Network (ANN), owned by the United Group media conglomerate.
