British police to fly to Moscow in poison spy probe

Detectives in the UK investigating the death of ex-KGB spy Alexander Litvinenko were tonight planning to fly to Moscow in their hunt for clues into the dissident’s poisoning, sources have confirmed.

It also emerged today that anti-terror police from Scotland Yard have already taken the investigation to the USA where they are thought to have interviewed a key figure behind the Ukrainian “Orange Revolution” of 2004.
