A former managing editor for the New York Post has sued the paper and its parent company, News Corp., claiming that she was demoted and later fired after complaining that an ex-editor-in-chief had propositioned her for sex.

The lawsuit, filed Tuesday morning by attorney Douglas Wigdor, alleged that higher-ups at the Post had purposely sidelined the plaintiff, Michelle Gotthelf, in retaliation for sounding the alarm about persistent sexual harassment by longtime editor-in-chief Col Allan, who was described as a “great friend and colleague” by News Corp. chairman Rupert Murdoch.
