Harris, 83, had previously been charged with nine charges of indecent assault involving two complainants dating back to the 1980s.

He was also facing four charges of making indecent images of children relating to alleged incidents last year.

The Crown Prosecution Service (CPS) now says the Australian will also face charges of alleged assault against females aged 19 in 1984, aged seven or eight in 1968 or 1969, and aged 14 in 1975.

The CPS says the allegations relate to one existing complainant and two new ones.

Most of the charges carry maximum sentences of five years in jail, while some carry a maximum of 10 years.

He appeared at Westminster Magistrates' Court in September, where he was granted bail, after being charged in August.

A preliminary hearing at the Old Bailey in October set his trial to start on April 30.

The charges came as a part of Operation Yewtree, the investigation prompted by the child sexual abuse allegations against late BBC TV presenter Jimmy Savile.

However, Harris's case relates to the third strand of Operation Yewtree, which is investigating allegations of abuse not related to the Savile scandal but which emerged in its wake.

The CPS has previously said there was sufficient evidence "for a realistic prospect of conviction".

Harris was first arrested in November 2012 over the allegations.
