Khodorkovsky gets six more years in Russia jail

Imprisoned oil tycoon Mikhail Khodorkovsky, once Russia's richest man, has been sentenced to six more years in jail.

His former business partner Platon Lebedev also faces a new prison sentence, correspondents report.

"Khodorkovsky and Lebedev may only be reformed if they are isolated from society," the judge's verdict says.

The two men were convicted of fraud on Monday in a judgment criticised by the US as selective justice.

The BBC's Daniel Sandford reports.
