Former chief medical officer for England Dame Sally Davies said she had nightmares about someone picking up the discarded nerve agent Novichok after the poisoning of former spy Sergei Skripal and his daughter, the Dawn Sturgess Inquiry heard.
Dawn Sturgess, 44, died after she was exposed to the chemical weapon, which was left in a discarded perfume bottle in Amesbury, Wiltshire, in July 2018.
