The EU boss snubbed the BBC as he embarked on a series of interviews with other European reporters.
Speaking from Strasbourg, BBC Daily Politics reporter Adam Fleming said: "There is a table and chair set up for President Juncker himself to come and do a series of interviews with European broadcasters
"Sadly he will not be doing one with me or the BBC. It's the remaining members of the EU only."
Mr Fleming's snub sparked questioning from BBC host Jo Coburn, who asked: "Have you been pushed to the back of the queue?"
