immunity@ (Adds Greek, Italy response)
MADRID, June 16 (Reuters) - The Eurogroup of finance ministers may block an 8.5-billion-euro ($9.5-billion) loan to Greece if it does not grant immunity to privatization agency officials from Spain, Italy and Slovakia, Spanish Economy Minister Luis de Guindos said on Friday.
In 2015, a Greek prosecutor charged three officials at the country's privatization agency with embezzlement for withholding interest payments and breach of duty in relation to a sale and lease-back deal of 28 state-owned buildings. The case is still pending.
"If there's not a definitive solution for the situation of these three experts, the Eurogroup will block the payment," de Guindos said in Luxemburg.
Greece would do "whatever necessary" to immediately settle the legal case, a Greek government official said.
European Economic and Monetary Affairs Commissioner Pierre Moscovici said he was confident the problem would be resolved and that he would continue to discuss the issue with Spain during his visit to Madrid next week.
"The problem has to be solved. We should not over dramatize it. The disbursement will happen and at the same time will find a solution to this problem," Moscovici said on his arrival at a meeting of EU finance ministers in Luxemburg on Friday.
On Thursday, euro zone governments threw Greece the latest financial lifeline and sketched new details on possible debt relief, allowing Athens to avoid defaulting on bailout repayments next month.
Italy's Economy Minister Pier Carlo Padoan said the disbursement of the 8.5-billion-euro loan would continue as the progress on the officials' case was assessed and that he was optimistic of a quick solution.
