A boy fell ill after coming into contact with Sergei Skripal the day he and his daughter Yulia were poisoned with Novichock, it has been revealed.

The Dawn Sturgess Inquiry was yesterday shown CCTV of Mr Skripal interacting with the child, handing him bread to feed ducks in Salisbury.

The boy, along with two others with him, were later traced as part of the investigation, and reported being ill for a day or two after the encounter.

However, the inquiry heard no traces of the chemical weapon were found on them when they were eventually tested.

After opening in Salisbury’s Guildhall earlier this month, the inquiry into Ms Sturgess’ death has resumed in London.

Ms Sturgess, 44, died after being exposed to Novichok in Amesbury, Wiltshire, in July 2018.

She sprayed herself with a “significant amount” of the nerve agent, which was hidden in a perfume bottle that had been found in a charity collection bin by her partner Charlie Rowley

The inquiry is in the process of hearing evidence about links between her death and the attempted murder of former Russian double agent Mr Skripal and his daughter in March 2018.

The UK security services blamed Russia for the attack.
