MOSCOW, Jan 15 (Reuters) - Russia on Thursday expelled a British diplomat it said was an undeclared spy, but London said such "malicious and baseless" accusations undermined the basic conditions needed for embassies to operate and said it was considering a response.
The FSB, the main successor to the Soviet-era KGB, named the British diplomat as Gareth Samuel Davies, a second secretary at the Moscow embassy, and said he was working undercover for Britain's intelligence service.
