Prosecution has demanded heavy jail sentences for former bosses of the oil giant Elf Aquitaine over their dealings in Africa. Prosecutor Catherine Pignon asked a Paris court to sentence André Tarallo, formerly the company's top manager for Africa affairs, to eight years imprisonment and to impose a fine of 5.8 million dollars. This is the first move by the prosecution against the top bosses of the company. Tarallo, 76, who came to be known as Elf Aquitaine's 'Monsieur Africa', managed the company's business in Africa for 20 years from the late seventies.
