Silvio Berlusconi, the leader of the party Forza Italia, has been transported by ambulance to Milan's San Raffaele hospital after suffering abdominal pain, daily newspaper Corriere della Serra reported.
"Prime Minister Silvio Berlusconi went to the San Raffaele this morning for treatment for acute renal colic. As soon as checks currently being carried out are over, he has promised to be present at the Forza Italia event scheduled for this afternoon with the European election candidates", a source close to Berlusconi told the media outlet.
The condition of the 82-year-old is unknown; Italy's former prime minister underwent routine checks earlier this year, but there were no reports of any health issues.
Back in 2013, Italy's former prime minister was sentenced to four years in prison on tax fraud charges, three of which were automatically pardoned, while the remaining 12 months were replaced by community work due to the politician's advanced age.
His conviction, however, caused the Senate to bar him from running for public office for six years — a decision that was overturned by a Milan court in May 2018.
