Salisbury poisoning nerve agent delivered to UK in ‘liquid form’

New light has been shed on the nerve agent attack on former Russian spy Sergei Skripal and his daughter Yulia. The Environment Department has said that only a “very small amount” was used in “liquid form” to poison the pair who were found unconscious on a bench in Salisbury last month. The government also gave details about the multi-million pound clean-up operation in the city.
