Veteran Australian entertainer Rolf Harris groped several women and girls in public, including a blind woman, British prosecutors have said.

The former television presenter, 86, is on trial for seven counts of indecent assault and one of sexual assault which allegedly took place between 1971 and 2003.

A judge ruled in December that Mr Harris, who denies the allegations, did not have to attend the trial in person due to his age and health.

He watched the hearing at a London court via video link.

Mr Harris has been a household name for more than 50 years as a television presenter, musician and songwriter.

One alleged victim, an adult at the time who is blind and suffers from cerebral palsy, claims Mr Harris touched her breasts when he was a guest on a hospital radio show that she presented in 1976.

Mr Harris "kissed the back of her neck and ... began slobbering over her" at the start of the alleged assault, prosecutor Jonathan Rees told jurors.

Another woman said Mr Harris put his hand up her skirt when she was 12, as she and her mother approached him for an autograph.

"Whether it was Mr Harris's celebrity status that apparently made him so brazen is something that you may wish to consider," Mr Rees said.

The trial is expected to last around six weeks.
