Pair 'poisoned by nerve agent'

Pair found unconscious in Wiltshire poisoned with same nerve agent as ex-Russian spy Sergei Skripal, police say.

The couple, believed to be Charlie Rowley and Dawn Sturgess, are in a critical condition having been found unconscious at a house on Saturday.

Police say no one else has presented with the same symptoms.

There was "nothing in their background" to suggest the pair were targeted, the Met Police said.

Metropolitan Police Assistant Commissioner Neil Basu said it could not be confirmed whether the nerve agent came from the same batch that Mr Skripal, and his daughter Yulia, were exposed to
