PCC’s thoughts remain with the victims and their families.
PCC Philip Wilkinson's statement after today's announcement.
He said: “My thoughts, and those of my office, remain with Dawn Sturgess' family and friends, alongside the other victims who have had their lives devastated by this incident.
"While today's announcement is important, it is vital we remember a member of our community was killed and others left changed and traumatised by the barbaric use of a nerve agent on UK soil.
"Our community has rebuilt, and those other victims are coming to terms with the long-lasting implications, so my hope now is the perpetrators will have their appalling crimes levelled against them and all of the victims will see justice served in their names.
"I am democratically elected to hold our police force to account, it would be widely welcomed if some foreign security services demonstrated that same accountability."
