Christine Lagarde, head of the International Monetary Fund, has hit back at Greece over claims that the IMF is seeking to push the country towards default, describing the idea as "nonsense".
In a terse letter to Alexis Tsipras, Greek prime minister, Ms Lagarde defended IMF staff who have found themselves at the centre of a furore over a leaked transcript of a teleconference where they discuss difficult bailout negotiations.
Mr Tsipras has argued the leaked transcript of the mid-March call, which was published by WikiLeaks, raised the question of whether Athens can continue to deal with two officials on the call, Poul Thomsen, head of the IMF's European bureau, and Delia Valculescu, who oversees the Greek programme for the IMF. But Ms Lagarde said her team "consists of experienced staff who have my full confidence and personal backing".
Ms Lagarde falls short of accusing Athens of being responsible for spying on her officials, but she warns Mr Tsipras that "it is critical that your authorities ensure an environment that respects the privacy of their internal discussions".
