When Epstein commented in an email about Varoufakis and Tsipras after the referendum

During the 2015 referendum, he appears to be talking with Ariane de Rothschild, head of the Edmond de Rothschild Group, one of the oldest and most powerful financial institutions in Europe, about the political developments at the time, with the dismissal of Varoufakis.

Thus, a few hours after the referendum of July 5, 2015, Rothschild tells Epstein that the information is "circulating strongly" that Alexis Tsipras wanted to remove Yanis Varoufakis and that it is considered certain that the chief negotiator Euclid Tsakalotos would take his place.

“I hear that Alexis Tsipras wanted Yanis Varoufakis’ “head” and got it. Should be replaced  by the chief negotiator Euclide Tsakalotos. But Tsipras will gain time Tomorrow's Eurozone Summit - they expect solution there."

Epstein retorts saying: "The Greek minister resigning, presents Greece a tougher problem - not easier, now they will be asked to come with a solution, no offers. Now they are truly f@@@@@i.”
