Russian hedge fund Hermitage Capital has vowed to name those it believes are guilty of a "conspiracy" against the firm, after a protracted dispute with the country’s government today led to an arrest warrant being issued for co-founder William Browder on allegations of tax evasion.

Russia's Ministry of Interior this morning said it had charged Sergey Magnitskiy, Hermitage's Moscow-based legal adviser, with tax evasion and issued the warrant on Browder for allegedly doing the same.
