Britain’s counter-terrorism chief has said it is highly likely the novichok that killed Dawn Sturgess in Wiltshire came from the same batch used four months earlier to attack a former Russian spy and his daughter at their Salisbury home.

The Metropolitan police assistant commissioner Neil Basu also said the substance that led to Sturgess and her partner Charlie Rowley falling ill on Saturday was in a vessel or container when the couple came across it. Police have opened a murder investigation after Sturgess died in hospital on Sunday at 8.26pm. Basu said: “It is both shocking and utterly appalling that a British citizen has died having being exposed to a Novichok nerve agent. “But make no mistake, we’re determined to find out how Dawn and her partner, Charlie Rowley, came into contact with such a deadly substance; and we will do everything we possibly can to bring those responsible to justice.”(theguardian)…[+]
