A TV station has been flooded with complaints after broadcasting an interview with a headmistress - showing a giant cartoon penis drawn on the blackboard behind her.

Head teacher Maria Franikova was being interviewed in a classroom at her school in Poltar, Slovakia, about an upcoming staff strike.

But no-one noticed the drawing on the board behind her - featuring a man with a penis for a nose - until viewers began to jam the switchboard at broadcasters Televizne Noviny's studios.
