"I am strictly against a European superstate. We are not the United States of America, we are the European Union, which is a rich body because we have these 27-28 nations. The European Union cannot be built against the European nations. This is total nonsense," Juncker told reporters.
Earlier in the day, the UK foreign secretary said that Brexit represented a "natural desire for self-government of the people, by the people, for the people." According to Johnson, Brexit diverges with EU politicians’ plan to "create an overarching European state as the basis for a new sense of European political identity."
During the Brexit referendum campaign, Johnson in particular accused EU leaders of having the desire to create a superstate and even drew parallels between the current situation and "different methods" used by Napoleon Bonaparte or Adolf Hitler.
In his speech, the European Commission head also touched upon recent Turkey's actions in the Aegean Sea, following an incident between Turkish and Greek vessels.
"I am strictly against the behavior of Turkey," Juncker said when asked about his reaction to the incident.
