The boss of Russian oil major Rosneft has been ordered to appear as a witness in an alleged bribery case, according to news agency Reuters.
The wire service has reported that a Russian judge ordered Igor Sechin to appear at the trial of ex-economy minister Alexei Ulyukayev.
Ulyukayev was dismissed and put under house arrest in November over allegations he extorted a $2 million (£1.5 million) bribe from Rosneft. He denies the charges.
The former minister was detained at Rosneft’s Moscow headquarters.
