Greek Finance Minister Yanis Varoufakis denied in an interview to the German newspaper Die Zeit on Wednesday that he was sidelined from debt talks between Greece and its creditors.

"Yes, I'm in charge. I'm still responsible for the talks with the Eurogroup," Varoufakis said.

Greek Prime Minister Alexis Tsipras reshuffled his team negotiating with European and IMF creditors on Monday. Deputy Foreign Minister, Euclid Tsakalotos, was appointed co-coordinator of the team.
