Max Clifford has been told his historic indecent assaults on young women would have resulted in an even more severe punishment had the offences been committed in recent years.
Judge Anthony Leonard said Clifford was charged under an act from 1956, which set the maximum term for such assaults at two years, because his offences took place between 1977 and 1984.
The judge said under later legislation passed in 2003, the maximum term would have been 10 years.
The worst instances would have been charged as rape or assault by penetration, which attract a maximum life term, Southwark Crown Court heard.
