French's president wife a beautiful mum: Berlusconi

Former Italian prime minister Silvio Berlusconi has joked about the the age gap between French's new President Emmanuel Macron and his wife, Brigitte Macron, calling her the leader's "beautiful mum."

"We have a 39-year-old guy [as French president] with, however, good work experiences, and, above all, with a beautiful mum who has taken him by the arm ever since he was a boy," Berlusconi said during a campaign event in Monza, near Milan.

Brigitte Macron, 64 is almost 25-year older than President Emmanuel Macron who is 39.

The first couple started an affair when she was Macron's high school teacher.

Berlusconi who himself no stranger to inter-generational love affairs, has a girlfriend Francesca Pascale who is 49 years his junior.

The former PM was also tried for soliciting sex from a minor in the so-called bunga bunga affair, but was acquitted for lack of evidence.
