Junker's position is entirely clear. He has agreed with the President of the European Commission and the President of the European Council, who when asked specifically about Scotland said:
"A new independent state would, by the fact of its independence, would become a third country with respect to the EU".
"A new state, if it wants to join the European Union,has to apply to become a member of the EU, like any state."
Juncker also added, "One does not become a member of the EU by sending a letter".
