The transcript shows IMF officials fretting that despite public claims eurozoneleaders wanted to move quickly to agree debt relief — which has long been an IMF demand, since Mr Thomsen believes Greece cannot survive economically with a large-scale restructuring — a decision will probably be delayed until July, when Greece is faced with its next big debt payment.
"What is going to bring it all to a decision point? In the past there has been only one time when the decision has been made and then that was when they were about to run out of money seriously and to default," Mr Thomsen is quoted as saying. "And possibly this is what is going to happen again. In that case, it drags on until July."
But Mr Thomsen notes that in addition to causing instability in Greece, a drawn-out deliberation on debt relief is politically dangerous for the EU because it will coincide with strife prompted by the refugee crisis and play out at the same time as Britain's June 23 referendum on EU membership.
"Clearly the Europeans are not going to have any discussion a month before the Brexit [vote] and so, at some stage, they will want to take a break and then want to start again after the European referendum," Mr Thomsen says.
Olga Gerovasili, a Greek government spokesman, said the statement showed MrThomsen was pushing for a Greek default before the British referendum in June.
\"The Greek government asks the IMF for explanations whether pursuing the creation of bankruptcy conditions in Greece, just before the British referendum, is the Fund's official position," Ms Gerovasili said.
A spokesman for Ms Merkel did not immediately respond to a request for comment.
Although much of the transcript reiterates well-known IMF positions on Greece, it lays out in clear detail the profound differences between Mr Thomsen and the European Commission, and highlights the IMF's belief that Brussels no longer has any credibility in judging Greece's fiscal and economic performance. The IMF and the commission are the bailout's two leading monitors and have clashed for months over how to proceed with the programme.
Delia Velculescu, who oversees the Greek programme for the IMF, is quoted showing frustration with the European Commission's backsliding on reforms required by Athens and says eurozone finance ministers should be forced to decide whether to accept the IMF's pessimistic view of the bailout's likelihood of success or a more optimistic view from Brussels.
"They need to take a stand on whether they believe our projections or the commission's projections," Ms Velculescu says.
Despite Greek anger over the disclosure, the transcript also shows the IMF arguing on Greece's behalf, saying it wants to ease off tough budget surplus targets and grant Athens significant debt relief — both policies Mr Tsipras has long asked for.
"I hope for the sake of the Greeks we are going to find a solution soon," MrThomsen says.
