Pietro Attardo, spokesman for the magazine Okay, said: "We wanted to offer something that beats the free music CDs or posters that our rivals were offering."

The offer was to mark the mag's 20th anniversary and every reader was offered a free trip to an 'erotic studio' including free sexual services.

Free Sex Commercial

But Swiss MP Heiner Studer said: "It's a disgrace, this magazine is not even classed as an adult magazine."

The magazine's campaign was an instant hit after some local radio stations refused to carry adverts promoting the unusual offer - which was then written about in Swiss media.

Attardo added: "I don't know why the radio stations refused to carry the advert, every man wants free sex."
