Was the attack the work of rogue Russia security agents – or a chilling message from Putin?
For a man who lived in a modest semi-detached house in a cul-de-sac in the genteel cathedral city of Salisbury, Sergei Skripal had a very immodest past. Some reports suggest that the former officer with Russia’s military intelligence service, the GRU, shared with MI6 the identities of as many as 300 Russian agents during his time as a double agent.
At his trial, the Federal Security Service (FSB, the successor to the KGB) compared Skripal to Oleg Penkovsky, who was executed in 1963, and who history records as one of western intelligence’s most valuable assets.
