Russia accused Britain of political censorship Monday after a British state-owned bank withdrew its services from Kremlin-backed Russian broadcaster RT.

RT said NatWest, owned by Royal Bank of Scotland Group (RBS), which is majority-controlled by the British government, had not explained why it was withdrawing its banking services in Britain and accused the bank of attacking freedom of speech.

In a letter published on RT's website, NatWest said it had decided to withdraw its services after "careful consideration." It did not offer an explanation for what it said was a final ruling, but said it would cancel RT's services from Dec. 12.
