An article in the Financial Times states that within the ruling SYRIZA party there are voices against the measures proposed to creditors by the Greek Prime Minister.
Shortly before leaving for Brussels, the Greek Prime Minister accused Greece’s creditors of maintaining a "strange position". Either they do not want an agreement or they are serving specific interests in Greece.
German sources indicate that creditors had addressed the invitation personally to Alexis Tsipras due to their unwillingness to negotiate with Minister of Finance Yanis Varoufakis.
