A 60-year-old man from Victoria has admitted to raping and sexually molesting his two step-daughters, who at the time of the assault were under 15 years of age.

His lawyers have also agreed for the man to be sentenced to 12 years' imprisonment instead of undergoing a trial by jury.

He was also accused of raping his own daughter, however she later withdrew her report, and this was accepted by the court.

The man was initially facing a life-imprisonment sentence after the Attorney General lawyer requested the punishment to be increased with an additional two degrees, which meant that he was going to be awarded a double punishment.

In their objection, the defence team remarked that the punishment needs to be corrected to the proper limits the offence carries. Therefore, a bargaining plea of 12 years imprisonment was later agreed to by the parties, and the accused accepted and admitted to the charges.

The sentence is to be delivered later on this month.

The court was presided over by Judge Natasha Galea Sciberras.

The accused was assisted by Daniel Tabone and Jose Herrera.
