The Italian stock exchange today said it has suspended indefinitely shares in Parmalat after the food and dairy group was declared insolvent over the weekend.
Yesterday, Italian prosecutors questioned former Parmalat chief executive Mr Calisto Tanzi in connection with alleged false accounting and market-rigging at Parmalat.
Mr Tanzi is at the centre of an inquiry into one of Europe's biggest corporate scandals, which involved the creation of fictitious assets in offshore front companies to conceal Parmalat's debts.
The scandal raises questions about the role of regulators, auditors, banks and executives in overseeing businesses that operate sophisticated global financial structures.
