Do members of the board still believe the Litvinenko story ? What's become clearer with time is that Litvinenko was a cog in a disinfo campaign to paint Putin's regime as being a trader in radioactive material that could be used for a dirty bomb. Evidence seems to point to the entire operation being controlled by the late anti-Putin oligarch, Beresovsky.
Now another UK IC asset going down. I'd be very skeptical of HMG's narrative. My scepticism is informed by recent events ; The Iraq dodgy dossier; the Steel dossier; The white-washing inquests into the deaths of Dr. David Kelly and Litvinenko etc.
Perhaps this unfortunate fellow ate Kimchi ?
