The 'messy' assassination attempt on Sergei Skripal and his daughter on a rainy day in Salisbury may have led to Novichok getting on their shoes and being spread further than thought across the city with every footstep, it was claimed today.
The desperate clear-up is continuing today two months after the first ever nerve agent attack on British soil took place ins Wiltshire.
The so called 'Novichok trail' that crosses Salisbury may have got worse because the nerve agent may have been on Sergei and Yulia Skripal's hands and feet.
Experts believe that the weapon was smeared on the handle of Sergei's front door but the 'messy' attack and heavy rain saw it diluted and spread on the step and drive.
The Novichok came in gel form but with traces of it all over the place for two miles it has not been possible to locate when exactly it was administered - and the zone could be larger than thought.
