“The answer is no,” spokesman Margaritis Schinas said on Wednesday when asked if, in the light of media reports about Juncker’s health, he would resign in the event of a “Brexit”.
He said Juncker had not played a more vocal role in the campaign because the Commission “was not and is not part of the campaign taking place in the UK”.
“It is an issue for the British people.”
The high stakes in Britain’s referendum have led to speculation about the fate of a series of political figures, not least British Prime Minister David Cameron, if Britain leaves the 28-nation union.
Former Luxembourg prime minister Juncker, 61, warned Britain on Tuesday that voting to leave the bloc would be “an act of self-harm”.
He insisted last week that the EU was not “in danger of death” if Britain departs, but that it would have to learn lessons.
