ITALIAN Premier Paolo Gentiloni is reportedly in good condition after undergoing heart artery surgery upon his return from a bilateral meeting in Paris.

Gentiloni’s office confirmed the 62-year-old leader was taken to Rome’s Gemelli hospital, but would not confirm why. News reports later said Gentiloni – who took office last month – had undergone angioplasty surgery.

Gentiloni - who was was foreign minister in Premier Matteo Renzi's government - met with French President Francois Hollande in Paris on Tuesday, on the first of the customary round of official visits by an Italian head of government after taking office.

He decided to get checked at the Gemelli after feeling unwell after landing in Rome, according to media reports, adding that he remained "lucid and on his feet".

The Italian may now cancel a proposed meeting with Theresa May today.
