Afghan refugee or Russian spy? The Times reveals the story of a man who accessed top-secret British files. The alleged spy, known as C2, entered the United Kingdom in 2000 - according to the newspaper - and was granted asylum after claiming that he fled the Taliban.
He denied being an agent, but revealed that MI5 accused him of being trained since he was five years old by Russian military intelligence. London accused Moscow of responsibility for the poisoning and killing of Alexander Litvinenko with polonium in London.
