The head of the European Commission had to interrupt his vacation in Austria because of his health. He returned to Luxembourg, where he will have an operation.

The Chairman of the European Commission 64-year-old Jean-Claude Juncker needed an urgent operation to remove the gallbladder. He interrupted his vacation, according to the EC website.

Juncker spent his vacation in Austria. “He was taken back to Luxembourg, where he has urgently carried out cholecystectomy (surgery to remove the gallbladder) — said in a statement.

When the operation will take place and how the state of the EC head is evaluated by doctors, is not specified. Next week Juncker should participate in the G7 summit, which will be held in French Biarritz.

As Bloomberg notes, Juncker has experienced health problems before — last year at the NATO summit he had an attack of painful radiculitis, accompanied by convulsions.

Juncker was born in 1954. He was Minister of Finance (1989-2009) and Prime Minister (1995-2013) of Luxembourg. In 2014, the European Parliament elected him President of the European Commission. His candidacy was supported, including German Chancellor Angela Merkel, while David Cameron, who at that time held the post of British Prime Minister, opposed.

Juncker will serve as head of the EC until October when former German Defense Minister Ursula von der Leyen will replace him. She’ll be the first woman in the office. Von der Leyen promised to distribute equally the posts of 28 members of the Commission between men and women.
