 Good morning, I'm Jonathan Fruin at the BBC. The head of Japan's navy is stepping down after more than 200 defence personnel were punished for a series of security breaches and fraud. The BBC's Mickey Bristow has more. The 200 sailors caught up in the investigation faced punishments that ranged from dismissal to reprimand. Admiral Yo Sakai apologised for the lapses and resigned. Japan is trying to strengthen its defence forces as it faces a more assertive China.
