FOR the Japanese political and parliamentary systems which seem unable to produce a prime minister with any staying power. This week Naoto Kan who has been in office for 15 months announced his resignation, claiming that during a period including a devastating tsunami and a continuing nuclear power disaster he had done everything I had to do. Not everyone will agree with that self-assessment and Mr Kan, Japan's sixth prime minister in five years, will soon be forgotten like his predecessors.
A Big Boo...
