Tracy Daszkiewicz was Wiltshire Council's director of public health when ex-Russian spy Sergei Skripal and his daughter Yulia were targeted in March 2018 with the deadly nerve agent novichok.
Three months after the Salisbury poisonings, two other people fell ill at a flat several miles away in Amesbury and one of them died.
Later this month, an inquiry into Dawn Sturgess' death will have another preliminary hearing.
On the Sky News Daily, Niall Paterson speaks to Ms Daszkiewicz about the impact Ms Sturges' death had on her and how she felt about being depicted in a TV drama about the poisonings.
