The next piece of financial aid to Greece from its euro zone lenders may not be imminent as talks are still complicated, the head of euro zone finance ministers Jeroen Dijsselbloem  said on Monday, adding that the target was to secure a deal as soon as possible.

“There is still a lot of work to do,” Jeroen Dijsselbloem told a news conference after a meeting of finance ministers in Brussels.

“I want to temper expectations. There is no need for a disbursement in March, April or May,” he said. Greece will need new funds to pay its debt by July.

Dijsselbloem underlined that he hoped that a deal on Greek reforms and on the next disbursement can be reached “as soon as possible”, but declined to answer a question on whether the next loan will hinge on the participation of the International Monetary Fund to the bailout.

This is a condition imposed by Germany, although the IMF has not yet decided on its role in the Greek bailout.
