Greece has reached an agreement with international lenders on the terms of the release of further bailout aid to the country in May, Greek Finance Minister Yannis Stournaras said on Monday during an economic forum in Athens.

"We have a deal with troika," he announced, addressing the event.

Within minutes, Poul Thomsen, head of International Monetary Fund's mission to Greece, who was also among key speakers, confirmed the positive result which comes after marathon negotiations between the two sides this spring.

Stournaras is due to hold a meeting with envoys of international creditors to Athens, including Thomsen, later on Monday to finalize some aspects, before the unveiling of the full deal in coming hours.

In the meantime, the troika issued a statement on the conclusion of the latest review of the Greek austerity and reform program.

"Staff teams from the European Commission (EC), European Central Bank (ECB), and International Monetary Fund (IMF) have concluded their review mission to Greece. The mission has reached staff-level agreement with the authorities on the economic and financial policies needed to ensure the program remains on track to achieve its objectives," said the statement.
