(ANSA-AFP) - BUDAPEST, JUN 26 - Hungarian Prime Minister Viktor Orban said Thursday that a state-organised consultation gave him a "strong mandate" to oppose neighbouring Ukraine's EU accession at the European Union summit in Brussels. The nationalist leader -- Russia's closest partner in the European Union -- has raised a series of objections and obstacles to Kyiv's integration into the 27-nation bloc. Since such decisions require unanimity, that has brought the process to a standstill. While the latest Hungarian survey carries no legal weight, Orban has since 2015 frequently used such questionnaires, backed by extensive multimedia campaigns, to justify his opposition to key EU policies. Official results show that more than 95 percent of those who took part in the consultation rejected Ukraine's EU bid. According to the government about 2.3 million -- less than a third of Hungarian voters -- participated in the mail-in and online ballot, which was conducted over 67 days. (ANSA-AFP).
