Tepco investors launch lawsuit

Shareholders of Tokyo Electric Power Co, operator of the crippled Fukushima nuclear plant in northeast Japan, are suing the utility's executives for a record 5.5 trillion yen (£42.5bn) in compensation, lawyers said. In the biggest claim of its kind in Japan, 42 shareholders filed a lawsuit accusing 27 current and former Tepco directors of ignoring multiple warnings of a possible tsunami and of failing to prepare for a severe accident, lawyers for the shareholders said in a statement.
