Litvinenko's death suggests more and more that the FSB might be involved.
As I told a couple of posts ago, it would be unlikely that anyone else than the Federalnaya Sluzhba Bezopasnosti (F.S.B)and the Putin's government might be involved into Litvinenko's murder. Some argued that Berezovsky might be involved to set up Putin but even then, there would be a lot of other way to discredit him than to kill one of his most trustful agent with a very rare poison.
Mario Scaramella, a specialist of the cold war and of the Russian affairs revealed a couple of interesting details that seem to draw the direction of the investigation to Mother Russia as not only Litvinenko was on the track of Polikovskaya's murderers, but he was also friends of the chechens:

Also, Graeme Gill of the School of Economics and Political Science at Sydney University and specialist of Russia also share the idea that Alexander Litvinenko was murdered by the FSB for a series of reasons that look a lot like those I already mentioned before: http://www.abc.net.au/pm/content/2006/s1797094.htm
