It has been confirmed that the policeman who was first on the scene in the Salisbury nerve agent attack has returned to active duty.

Sergeant Nick Bailey was poisoned with Novichok after going to investigate the home of former Russian spy Sergei Skripal in March 2018.

At the time, Prime Minister Theresa May said the attack had "almost certainly" been approved by the Russian state.

In July, Dawn Sturgess 44 also came in to contact with Novichok after finding a discarded perfume bottle. She died in hospital.
