That means Juncker will miss the the G7 summit in Biarritz, France, which takes place 24-26 August.

Natasha Bertaud stated during a press conference on 19 August:

“As we announced over the weekend, President Juncker had to shorten his holidays in Austria for medical reasons. He was taken back to Luxembourg, where he was to undergo an urgent surgical removal of the gallbladder. That surgery took place during the weekend. And I can confirm that the surgery went well and that President Juncker currently remains in hospital, in recovery. His doctors have specified that he should not travel at this time. And then we are therefore also able to confirm that he will not be to attend this weekend’s G7 meeting.”

Bertaud said that Juncker “intends to take contact with” the French president, Emmanuel Macron, who chairs the G7 confab, and the European Council president, Donald Tusk, “to confirm arrangements” on how the EU will be represented at the summit.

Juncker served as Luxembourg prime minister between 1995 and 2013. He has been head of the EU executive since 2014 and his term will end in October of this year.

This was not the first time Juncker’s health has come into public view. Last summer he was seen stumbling during a Nato summit, which was blamed on sciatica.
