Public hearings begin on Monday at a British inquiry into the 2018 death of a woman who was exposed to the nerve agent Novichok used in an attempt to kill a Russian double agent, which plunged relations between London and the Kremlin to new lows.
The intended target of the poison attack was former double agent Sergei Skripal, who lived in Salisbury, southwest England, and on whom Russian President Vladimir Putin had sworn vengeance.
Skripal and his daughter Yulia were both found unconscious on a bench in the city center in March 2018. They survived after intensive treatment in hospital, and now live under protection.
