The clean-up and decontamination work at Zizzi Salisbury is complete, say the Department for Environment, Food and Rural Affairs.

A Defra spokeperson said: “Following extensive and meticulous clean-up work carried out by specialist military teams, Defra has given Zizzi Salisbury the all clear.

"The site has now been handed over to Wiltshire Council, who have in turn passed it back to the owners to begin refurbishment.

“Our number one priority is making all sites in South Wiltshire safe and our highly precautionary approach means residents and visitors can be fully confident that the restaurant is clean and can soon return to normal.”

The restaurant on Castle Street has been closed since March, after Sergei and Yulia Skripal visited the restaurant on the day they were poisoned.

Defra also said a more detailed announcement will be made in the next week.
