"If there is no prospect of a deal by Friday or Monday, I don't know by when exactly, we will not pay," Nikos Filis told Mega TV.

The June 5 payment of 300 million euros is the first of four this month totaling 1.6 billion euros. Athens depends on foreign aid to stay afloat.

Greek Prime Minister Alexis Tsipras will travel to Brussels on Wednesday for a meeting with European Commission President Jean-Claude Juncker as Athens and its lenders seek to agree on a deal that will unlock remaining bailout funds.
