(ANSA) - BELGRADE, OCT 1 - Hungarian Prime Minister Viktor Orban has rejected the idea of switching from unanimity to qualified majority voting to open the EU accession negotiations, which European Council President Antonio Costa intends to discuss at the Copenhagen summit. "Never. Ever. There is a very strict legal procedure. "We must follow it," the prime minister stated upon arriving at the summit. "Ukraine is a heroic country, we must support it. There's no doubt about it. The problem is the form. How will we do it? Membership is too much. We just need a strategic agreement. That's what I will support," he added. (ANSA).
