PR guru Max Clifford has been found guilty of a string of indecent assaults on teenage girls over a period of nearly 20 years.

The 71-year-old became the first person to be convicted under the high profile Operation Yewtree sex crime investigation at Southwark Crown Court today.

He was found guilty of eight indecent assaults, cleared of two and the jury was unable to reach a verdict on one other.

Clifford repeatedly denied the claims, calling his arrest and prosecution ''a nightmare'' and protesting his innocence.

He was arrested by detectives from Operation Yewtree in December 2012, and charged in April the following year.

The investigation, Scotland Yard's inquiry into historic allegations of sexual offences, was prompted after claims were made against the late DJ Jimmy Savile.
