Greek authorities have not yet responded to the BBC's findings. Also on the programme; the United States has given a positive assessment of talks between its top diplomat and China's foreign minister, but Beijing says relations are at a historic low. And, we hear how Swiss voters backed ambitious plans to save melting glaciers.
