Napolitano says he is worried by reports of bribery
'I await outcome of investigation' says Italian president15 February, 18:59
But he added everyone must wait for the outcome of judicial investigations into the claims.
"All this worries me but I know nothing, I am waiting for the outcome of the investigation", Napolitano told journalists, when asked if the current environment means a return to the era of the "Bribesville" scandals of the early 1990s.
The judiciary must determine whether "behind these international transactions there is something in the form of hidden reserves or kickbacks".
He spoke soon after Giuseppe Orsi, chief executive of Finmeccanica, resigned following his arrest on suspicion of international corruption and tax fraud over the sale of helicopters to India.
The Indian government cancelled the contract Friday over the investigation. Orsi continues to deny any wrongdoing and said his actions "had always been motivated by the exclusive interest of Finmeccanica and all its subsidiaries".
