Russian prosecutors on Friday said Mikhail Khodorkovsky, the jailed Yukos oil tycoon, laundered more than $23bn (€18bn, £12bn), in Yukos oil sales, disclosing the first details of charges that could keep the Kremlin opponent in jail for a further 10 years.

The prosecutors made their first full statement on fresh charges brought against Mr Khodorkovsky and his business partner Platon Lebedev earlier this week.
