Britain opposes curb on Russian trade over Ukraine crisis - BBC says

LONDON (Reuters) - Britain opposes trade sanctions on Russia and does not want to shut London's financial capital to Russians in response to the Kremlin's intervention in Ukraine, the BBC reported, citing a document which was inadvertently shown to a photographer.

British Prime Minister David Cameron has warned President Vladimir Putin that Russia will have to pay 'significant costs' unless the Kremlin changes course on Ukraine whose Crimea region is now controlled by Russian forces.
