The founder and former chairman of scandal-hit Italian food group Parmalat, Calisto Tanzi, has promised to tell prosecutors everything he knows about the company’s collapse in December 2003.

“I apologise to all those who have suffered or been damaged in ….(my) attempt to fulfil a project and an industrial dream,” Tanzi was quoted by Reuters as saying after a five-hour interrogation.

Tanzi also promised to name names, saying it was his duty to “collaborate fully with prosecutors to reconstruct … the causes of Parmalat’s sudden default (and) who is responsible”.

Tanzi is due to be questioned again by prosecutors in Parma on 22 January, reported Reuters.
