The Novichok attack left a trail of the deadly nerve agent around Salisbury, with mother-of-three Dawn Sturgess dying after she came into contact with the chemical. These are the two Russian spies being sought over the Novichok poisoning in Salisbury in March. On the Saturday, the day before the attack, they carried out a reconnaissance trip to Salisbury before returning to London. On the Sunday, they took another train to Salisbury and are thought to have smeared the Novichok on Mr Skripal's front door. The former spy was living at an address in Salisbury, Wiltshire, when the suspected poisoning took place in the city centre.
