Salisbury nerve agent attack decontamination could take months

Decontamination of sites affected by the Salisbury spy poisoning incident is expected to take "weeks or months" as the local authority admits the long-term health effects are still unknown.

Alistair Cunningham, corporate director of Wiltshire Council, told a cabinet meeting the UK Government had pledged £1m to help support businesses affected by the cordons which still seal off part of the city centre.
