Writer and former radio researcher Annette Sanderson is being sued for libel by her former colleague Jean Frazer Allardyce. Miss Sanderson does not deny that her comments were defamatory but argues they are true. She claimed that Miss Frazer was a manipulator who used sex to win people round to her side - including herself. She also alleged that Miss Frazer failed to give her proper credit for her part in a successful radio show, deceived listeners and even engineered her dismissal on the grounds of immoral conduct.
