Is BP getting cold feet in Russia?

A new investigation has been launched after claims a sister firm of the Russian-British oil company TNK-BP – Sedanko- didn't pay one billion roubles in taxes.

On Tuesday, it emerged 148 of TNK-BP’s foreign workers, mainly technicians and engineers, lost their work permits.

And last week Russia's security service raided the company's Moscow offices as an employee was charged with industrial espionage.
