Greece needs deal with lenders on April 24 -finance minister to paper

"At the Eurogroup (meeting) of April 24 there must be a preliminary conclusion (of the talks), as per the Eurogroup accord on Feb. 20," Yanis Varoufakis told daily Naftemporiki.

Greece offered a new package of reforms last week in the hope of unlocking remaining funds from its bailout program, but its EU and IMF lenders have yet to sign up to the proposals.

Gerda Hasselfeldt, a senior member of German Chancellor Angela Merkel's conservative allies in Bavaria, was quoted in a separate newspaper interview as saying Athens had "wasted precious time" since Germany's Bundestag lower house approved an extension of Greece's bailout in February.

She told Die Welt the question of a third aid program for Greece did not arise, adding: "If the (Greek) plans are not made more concrete, I don't see any leeway there."

Athens has not received bailout aid since August last year and has been hard pressed to cover payments amid a cash crunch, resorting to measures such as borrowing from state entities to tide it over.

A source with knowledge of the issue told Reuters last month that Greece had enough funds to last it until April 20.

Varoufakis said on Sunday following a meeting with International Monetary Fund chief Christine Lagarde that Greece intended to meet all obligations to all its creditors, moving to quell fears of a possible default ahead of a 450 million IMF euro loan repayment later this week.

He told Naftemporiki the new leftist-led government, confronted with a liquidity squeeze, wanted negotiations to be concluded "as soon as possible" but would not accept terms that suffocated the economy.

"We are not going to condemn the country, as previous governments did, to a long-term asphyxiation," Varoufakis told the paper, suggesting the EU/IMF lenders had treated the previous conservative-led government more leniently.

"The negotiations will end when we reach an honorable agreement, which will give the Greek economy the prospect of real stabilization and substantive growth," Varoufakis said.

Asked whether he had thought of quitting the job, said: "Not for one minute."
