(CP) Saskatchewan Premier Brad Wall has advised The Canadian Press he intends to sue the national news agency for defamation for a headline it ran on a story featuring controversial comments he made on a home-movie videotape made more than 16 years ago. The headline in question is “Tape with Sask premier and Tory MP has racist, sexist, homophobic comments: NDP,” whereas Wall claims he wasn’t in the room when most of those comments were made.
