Street artist Ben Eine has revealed that British Prime Minister David Cameron joked about Silvio Berlusconi’s taste for prostitutes with his wife Samatha before heading to Rome for a state dinner, the Guardian reports.

In 2010, a work by Eine was about to be given to President Barack Obama as an official gift. The artist was invited to have tea with the Prime Minister and his wife Samantha, just before Cameron had to leave for Italy.

According to Eine, who was speaking at the start of a three-day Street Art conference at London’s South Bank Centre, Cameron told his wife as he left the room:

“Samantha I’ve got to go off to Italy – dinner with Berlusconi. Don’t worry I’ll get so-and-so to pull me out of the jacuzzi before the whores turn up.”

Eine recalled: “I was like, that’s great, prime ministers aren’t meant to say that in front of bods like me, just in case I do this and repeat the story in front of a video camera.”

Italy’s former Prime Minister Berlusconi has been involved in several scandals involving prostitutes. In the most prominent case, he was accused, convicted, but found not guilty on appeal of buying sexual services from an underage sex worker, Karima El Mahroug, known as Ruby Rubacuori (“Ruby the Heart-stealer”).

A Downing Street representative told the Guardian they never comment on private conversations.
