New York: Fox News has decided to part ways with star host Bill O'Reilly following allegations of sexual harassment, 21st Century Fox confirmed in a statement on Wednesday.

O'Reilly, the arguably the biggest star on the conservative network, said in an April 1 statement that he had been unfairly targeted because of his public prominence. Marc Kasowitz, O'Reilly's lawyer, said in a statement on Tuesday that the television host "has been subjected to a brutal campaign of character assassination that is unprecedented in post-McCarthyist America."

The confirmation came after reports in two major news organisations, New York and The Wall Street Journal reported on Wednesday that the network was preparing to cut ties with O'Reilly.

"After a thorough and careful review of the allegations, the company and Bill O'Reilly have agreed that Bill O'Reilly will not be returning to the Fox News Channel," 21st Century Fox said in a statement.
