The IMF's admission on Greece comes from its own review of the conditions it imposed on the first bailout in 2010 and it highlights some key failings.
It said that it underestimated how much damage the austerity it imposed would do to Greece, it expected the economy to shrink by 5% but in fact it shrank by 17% between 2009 and 2012.
Also the IMF said that it lent too much to Greece, sums so vast that it cannot vouch for the fact that they will be repaid and it lowered its own standards in making those loans - essentially buying time to save the rest of the eurozone.
It does defend some of the reforms, including saying that lowering wages is helping to make Greece more competitive but overall I think this is a big admission it went too far, too fast and it has implications for other countries where the IMF doles out its prescriptions.
