ADVICE has now been issued to the public who have visited the potentially contaminated sites. 

A man and woman remain in critical condition in hosital after being exposed to the same nerve agent used to poison the Skripals.

Mike Wade, the deputy director of health protection for PHE South West, said there is "no significant health risk to the wider public", adding: "We will keep this assessment under constant review as further information becomes known."

A number of sites in Amesbury and Salisbury that the two visited before they fell ill, have been cordoned off.

Queen Elizabeth Gardens in Salisbury, a property at John Baker House, Rollestone Street, Salisbury, a Muggleton Road property, Boots the Chemist, Stonehenge Walk, Amesbury and Amesbury Baptist Centre have also been cordoned off. 

Mr Wade said: “While there is no immediate health risk to anyone who may have been in any of the five locations identified by police today, as a highly precautionary measure we are advising that people who visited the sites between 10pm on June 29 and 6.30pm on Saturday, June 30, undertake the following actions."

If you visited any of the five locations identified by police you should:

• Wash the clothing that you were wearing in an ordinary washing machine using your regular detergent at the temperature recommended for the clothing 

• Wipe personal items such as phones, handbags and other electronic items with cleansing or baby wipes and dispose of the wipes in the bin (ordinary domestic waste disposal)

• If your items are dry-clean only, you should keep them double-bagged and securely fastened. Further details will follow.

• None of these actions should damage your washing machine

• Other items such as jewellery and spectacles which cannot go in the washing machine or be cleaned with baby wipes, should be hand washed with warm water and detergent and then rinsed with clean cold water

• Please thoroughly wash your hands with soap and water after cleaning any items.

• You do not need to seek advice from a health professional unless you are experiencing symptoms.

The ambulance service was called to Muggleton Road on Saturday (June 30) at about 10.15am where a 44-year-old woman had collapsed. She was taken to hospital.

And at about 3.30pm, the ambulance were called to the same address where a 45-year-old man had also fallen ill. The man was taken to hospital and Wiltshire Police were informed.

The pair, who were taken to hospital on Saturday, have been named locally as Charlie Rowley and Dawn Sturgess.
