Naoto Kan, the former Prime Minister, has admitted that his office was "overwhelmed" during the Fukushima nuclear meltdown last year, and he recommended that Japan scrap all its reactors to avoid a repeat.
He told a parliamentary committee yesterday that the bulk of the blame for the disaster lay with the nuclear lobby, which he said had acted like the nation's out-of-control military during the Second World War, with "a grip on actual political power".
Mr Kan has been sharply criticised for his handling of the disaster.
