The Italian Football Federation's prosecutor Stefano Palazzi wants the clubs at the centre of match fixing accusations thrown out of Serie A, the top tier of Italian football. He called for Juventus to drop two divisions and for AC Milan, Fiorentina and Lazio to drop one.
He also asked for points penalties to be imposed and that Juve's 2005 and 2006 titles be stripped from the club.
Juventus shares dived on the Milan stock market following Palazzi's comments.
Earlier on Tuesday, the third day of Italy's biggest sports trial, Italian Football Federation (FIGC) official Paolo Bergamo resigned. He is one of two officials under suspicion involved in the allocation of referees - his lawyer unsuccessfully argued he was now no longer liable to be tried by a sports tribunal.
