Portugal's market regulator on Thursday halted trading in shares in the country's biggest bank Banco Espirito Santo after they plunged over allegations that its parent company covered up a 1.3 billion euro hole in the accounts.
Trading was suspended ahead of "important information" to be published by BES, the market regulator said. Shares in the firm had plummeted by 17.24 percent to 0.50 euros at the time of the suspension.
