She said the outstanding details are expected to be finalised later on Tuesday.

She also said deputy finance ministers from the 28 EU countries are to hold a telephone conference on Tuesday afternoon to “take stock”.

She noted the political process is already underway, with commission head Jean-Claude Juncker having spoken by phone with Germany’s finance minister Wolfgang Schaeuble and with the Greek PM Alexis Tsipras on Monday.

Juncker also plans to speak with German chancellor Angela Merkel and with French president Francois Hollande by phone on Tuesday.

Breidthardt said the technical talks, at the Hilton hotel in Athens, are being conducted by the “mission chiefs” of the commission, the European Central Bank (ECB), the International Monetary Fund (IMF,) and the Greek finance ministry.

She declined to give further information.

But the fact the IMF representative has endorsed the agreement increases expectation the Washington-based body will take part in the new bailout.

The IMF previously said it will only join in if there is a restructuring of Greek debt, an idea disliked in Germany.

For its part, Greece’s Skai TV reports that of the 35 “prior actions” the creditors had asked for, the problematic details remain on: privatisations; non-performing bank loans; and energy liberalisation.

Greek officials told the Kathimerini daily the deal is to be discussed by parliamentary commitees on Wednesday and voted on Thursday.

They also said the Greek PM, Alexis Tsipras, spoke by phone with the German chancellor and the French president on Monday.

If Tsipras gets the prior actions through parliament, euro-area finance ministers are likely to hold a snap meeting on Friday to discuss the accord.

The clock is ticking because Greece needs aid to repay an ECB loan on 20 August.

But Germany has said the deadline could be covered by a bridging loan instead of a full-blown bailout deal, worth up to €86 billion, if the bailout accord is not ready in time.

"We're talking about a program for three years, it needs to be negotiated thoroughly”, German deputy finance minister Jens Spahn told the ARD broadcaster on Tuesday morning.

"It must be convincing that it's not just about August 20”, he added.

“It's not just about making savings, that it works for the budget, but above all about how Greece ... earns money in the next few years, what is the 'business model' so to speak”.

Any political accord at euro finance ministers’ level will also have to be ratified by the Bundestag, and a handful of other euro parliaments.

But Tuesday’s news already prompted a rally on the Athens stock exchange and a drop in the cost of its two-year and 10-year bonds.
