Carrie Johnson has said there could be more than 1,000 victims of black cab rapist John Worboys. Ms Johnson, one of several women who spoke out to keep Worboys behind bars, appeared on Good Morning Britain on Wednesday (20 May) where she discussed her encounter with the convicted rapist at the age of 19. “The truth is that his crimes span from, what we know, from 2000 up to when he was convicted in 2009,” said Ms Johnson, the wife of former prime minister Boris Johnson. “And he was a cab driver for that duration, out potentially every night in his cab, so there could be up to 1,000 if not more than that.”
