A Swiss prosecutor confirmed on Wednesday (April 3) that disgraced Jerome Cahuzac had held a bank account in Switzerland, and that his office was cooperating with French authorities who are investigating the French former minister.

Prosecutor Yves Bertossa told a news conference that Cahuzac's admission that he had 600,000 euros in the account were plausible and that it has been in existence since the early 1990s.

French prosecutors began investigating Cahuzac for fraud after accusations by investigative news website Mediapart. If charged and found guilty in court, Cahuzac could face up to five years in prison.

Bertossa acted on a French request to obtain documents from UBS and Reyl & Cie, the two banks involved, his office said in a statement. Reyl and UBS both declined to comment.

Cahuzac said on Tuesday he had confirmed to investigating magistrates that an account existed although he had not deposited any money there for some 12 years. He said he had given instructions for the funds in it to be moved to his account in Paris.
