A former MI5 officer has poured scorn on speculation that Vladimir Putin's government was directly involved in the poisoning of Russian spy Sergei Skripal.
The former double agent, convicted of high treason in Russia in 2010, was found unconscious on a park bench earlier this week, along with his daughter. Both had been poisoned using a nerve agent in an attack widely attributed to the Kremlin.
But Annie Machon said "there are too many known unknowns at this point," adding that Skripal was "a busted flush" in terms of intelligence.
With this in mind, Machon speculated that there could be a "deeper motivation" at play, adding that perhaps "the fingers are [being] made to point towards Russia."
