Vladimir Putin has said Russia's most famous prisoner and the president's biggest political enemy, could soon be freed.
Mikhail Khodorkovsky, who has been in jail for more than 10 years, was head of the Yukos oil company before he was convicted of embezzlement, but he has always protested his innocence.
