LONDON (Reuters) – Britain’s business secretary Kwasi Kwarteng said on Sunday he welcomed BP’s decision to exit its 19.75% stake in Russian state-controlled oil firm Rosneft in the wake of Russia’s invasion of Ukraine. “Russia’s unprovoked invasion of Ukraine must be a wake up call for British businesses with commercial interests in (Russian President Vladimir) Putin’s Russia,” he said on Twitter.
