TRIBUTES were paid yesterday to a woman who died after exposure to an alleged nerve agent, as authorities said her death was being treated as murder.

Dawn Sturgess and her partner Charlie Rowley were poisoned in Salisbury on June 30. She died on Sunday and Mr Rowley remains critically ill.

Amesbury is the other side of Porton Down, which hosts a military laboratory, to Salisbury — where former Russian spy Sergei Skripal and his daughter Yulia were poisoned four months ago.

The Skripals are no longer seriously ill. In their case the government rushed, without presenting evidence, to blame their poisoning on the Russian government.

Showing more restraint this time, Home Secretary Sajid Javid said he wouldn’t “jump to conclusions.”

In the Commons, Labour leader Jeremy Corbyn said: “I’m shocked by the death of Dawn Sturgess. My thoughts are with her family and friends at this terrible time.

“A full and thorough police investigation must now establish the facts, provide support to the local community and bring those responsible to justice.”

Salisbury MP John Glen claimed that the poisoning of Ms Sturgess and Mr Rowley is “very likely the result of picking up a discarded container” from the poisoning of the Skripals.

But counter-terrorism officer Neil Basu said detectives can’t confirm if the same chemical is involved.
