By James Chapman Last updated at 1:40 AM on 10th September 2011 Russia is to offer to share its security secrets with Britain – but will rebuff demands to extradite the chief suspect in the radiation murder of a dissident in London. The revelations were made by Moscow’s ambassador Alexander Yakovenko in highly unusual public remarks ahead of a visit to the Russian capital by David Cameron next week. He insisted the Kremlin would not agree to send Andrei Lugavoy, prime suspect in the 2006 murder of dissident Alexander Litvinenko, for trial in Britain as Scotland Yard has demanded.
