Budapest - Mr Gyula Horn's position as Hungarian Prime Minister was seen as secure yesterday despite a call for resignation by a committee investigating the communist past of the country's senior officials. The committee of three judges invited Mr Horn to step down after establishing he had served in a paramilitary force which restored order after the 1956 anti-Stalinist uprising, and that as a senior foreign ministry official from 1985 to 1990 he received reports from the secret service monitoring dissidents. "I see neither a moral nor a legal reason to resign," Mr Horn said on Monday.
