Rolf Harris has been charged with 13 offences under Operation Yewtree, including nine counts of indecent assault and four counts of making indecent images of a child last year.

The 83-year-old Australian entertainer, who had a long career in British children's TV in the 1960s, 1970s and 1980s, is accused of three counts of indecently assaulting a 14-year-old girl in 1986 and six of indecently assaulting a girl aged between 15 and 16 from 1980 to 1981. He is also charged with four counts of making indecent images of a child between March and July 2012.

Harris, who will appear at Westminster magistrates court on 23 September, was initially interviewed under caution on 29 November last year under the Operation Yewtree investigation into alleged sexual offences by Jimmy Savile and others. He was then arrested on 28 March and bailed pending further inquiries.

The inquiry has been run in three strands – claims involving Savile, those involving Savile and others, and those involving others.

Harris is being dealt with under the "others" strand, meaning the allegations have no link to Savile.

Alison Saunders, chief crown prosecutor for CPS London, said: "We have carefully considered the evidence gathered by the Metropolitan police service as part of Operation Yewtree in relation to Rolf Harris, who was initially arrested on 29 November 2012 over allegations of sexual offences. A file of evidence was passed to the CPS on 12 August 2013.

"Having completed our review, we have concluded there is sufficient evidence and it is in the public interest for Mr Harris to be charged with nine counts of indecent assault and four of making indecent images of a child.

"The alleged indecent assaults date from 1980 to 1986 and relate to two complainants aged 14 and 15 at the time of the alleged offending.

"The decision has been taken in accordance with the code for crown prosecutors and the DPP's interim guidelines on prosecuting cases of child sexual abuse. We have determined that there is sufficient evidence for a realistic prospect of conviction and that a prosecution is in the public interest."

The Australian, who painted a portrait of the Queen in 2005 and performed at her Diamond Jubilee concert last year, has been a family favourite for decades.

Born in Perth, Western Australia, in 1930, Harris emigrated to the UK at the age of 21. He enrolled an art school, but, after two years, he dropped out and instead started drawing on children's television programmes.

A successful career in television hosting programmes such as The Rolf Harris Show, Cartoon Time and Animal Hospital followed. That was accompanied by a substantial musical output that comprised 30 studio albums and 48 singles – including Tie Me Kangaroo Down, Sport and Two Little Boys, which went to number one in 1969.

He continued to enjoy success in the industry, gaining cult status in recent years and performing at Glastonbury festival several times.

Harris, who has lived in Bray, Berkshire, for more than 50 years, was awarded an MBE in 1968, an OBE in 1977 and a CBE in 2006, and was made Officer of the Order of Australia in the Queen's Birthday Honours list last year.
