(ANSA) - BELGRADE, APR 21 - Serbian President Aleksandar Vučić stated that the rector of the University of Belgrade, a potential opposition leader, did not have the right to speak with Marta Kos yesterday. Furthermore, there has been little or no official political reaction in Serbia to the EU Commissioner for Enlargement's criticisms of Serbia's rule of law, judiciary independence, "student repression, and interference in independent media" yesterday in Belgrade, calling the future of €1.5 billion in Growth Plan funding into question. From an administrative standpoint, the only adjustment to Brussels' concerns is the government's directive to state authorities to "harmonise regulations—laws or regulations—with the acquis communautaire." Vučić did not respond to the EU Commission's comments, but instead took aim at the rector of the University of Belgrade, Vladan Djokic, who is unofficially tipped as a potential political candidate for the student protest movement in the upcoming Serbian elections. Djokic flew to Brussels yesterday to meet with Commissioner Kos, just hours before her scheduled appearance before the European Parliament's Foreign Affairs Committee. According to Tanjug, Vučić argued that the EU violated the rule of law by allowing the rector to engage in politics despite not resigning from his post. According to independent broadcaster N1, Vučić added that in the EU, "they talk a lot about the rule of law," but then violate these principles whenever they feel like it, while they are masters at lecturing others. But you'll see that everything will be fine once Serbia meets the necessary requirements." (ANSA).
