Fayed was a "serial sexual abuser" whose abuse was "constant and repetitive" over 25 years, barrister Dean Armstrong KC said.
"I have many years of practice... I have never seen a case as horrific as this," he told the news conference.
This case combines some of the most horrific elements of the cases involving Jimmy Savile, Jeffrey Epstein and Harvey Weinstein.
Savile because in this case, as in that, the institution, we say, knew about the behaviour", Mr Armstrong continued.
Epstein because in that case, as in this, there was a procurement system in place to source the women and girls. As you know, there are some very young victims.
And Weinstein, because it was a person at the very top of the organisation who was abusing his power.
We will say plainly, Mohammed Al Fayed was a monster."
