Former Italian prime minister Silvio Berlusconi has been urgently admitted to hospital in Monaco because of heart problems, his personal doctor says.
Alberto Zangrillo said he saw Berlusconi on Monday and decided to transfer him to a nearby hospital because he did not think it prudent to bring him to Italy, which is 15km from the small city-state.
Italy's ANSA news agency first reported the news.
It was not immediately clear if the health emergency had been overcome.
The 84-year-old media tycoon underwent major heart surgery in 2016 and has also survived prostate cancer.
Last September he was hospitalised after contracting coronavirus.
He later told reporters that the virus had posed "the most dangerous challenge" of his life.
Berlusconi remains the head of the opposition Forza Italia party.
Newspapers have speculated that some Forza Italia lawmakers might agree to help prop up the administration to prevent early elections.
