Salisbury has been declared Novichok-free almost a year after the poisoning of Sergei and Yulia Skripal. The last of the 12 potentially infected sites was ruled safe on Friday, bringing an end to the clean-up exercise. The investigation into last year's incidents in Salisbury and Amesbury is still ongoing. Wiltshire Police have appealed for people to come forward with any information on what happened.
