VETERAN entertainer Rolf Harris saw his decades in the spotlight end in disgrace today as he was found guilty of indecent assault.

The 84-year-old, once a much-loved artist and musician, was convicted at Southwark Crown Court of 12 sex charges involving four women.

His army of supporters, including suited security guards and representatives from PR giant Bell Pottinger who attended every day of the trial, could do nothing to change the verdict of the jury of six men and six women.

Once seen by a UK audience as a national treasure, Harris had enjoyed years of success, netting him a multi-million pound fortune and the chance to paint the Queen.

But the downfall of an entertainer who was part of millions of British childhoods came today, as Harris became the biggest scalp claimed by detectives from high profile sex crime investigation Operation Yewtree.

Dozens more alleged victims have come forward during the trial, including several in Australia, and Scotland Yard has been in touch with their counterparts in the Australian police, but it is not yet clear whether they are pursuing any investigation in Harris's home country.

The NSPCC said it has received 28 calls relating to Harris to date, involving 13 people who claim they fell prey to the performer.

Harris remained impassive as the forewoman delivered the unanimous verdicts.

His daughter Bindi held hands with a fellow supporter, and wife Alwen and niece Jenny also watched from the public gallery as his fate was sealed.

The performer was released on bail until Friday when he will be sentenced.

Justice Sweeney warned the 84-year-old that given the conviction on all 12 counts it was "inevitable" that a custodial sentence would be possible.

"He must understand that", he said, to which Harris's barrister Sonia Woodley replied: "He does appreciate that".

The judge told the jury: "During the case you will have had to grapple with a side of life which I suspect you would prefer not to have had to grapple with.

"You have done so in the face of daily attention of large numbers of members of the media representing the public and observation of how you have conducted yourselves."

He excused them from jury service for 10 years.
