Russian diplomats to be expelled over spy attack
Sky Sources: PM to announce expulsion of Russian diplomats as part of a range of measures in response to Salisbury poisoning.
Sky's Defence Correspondent Alistair Bunkall says it will not involve as many as the number expelled in 1971.
He adds: "Not sure if the Russian Ambassador will be expelled but I’m told the UK wants to retain the ability to have dialogue."
Earlier, Britain's former ambassador to the United States, Sir Christopher Meyer, told Sky News he hoped for a "smart" response from Theresa May.
"All of the protocols of the Cold War no longer exist," he said.
"What we have entered is a 'wild West' behaviour - particularly by the Russians who have invaded Ukraine, seized Crimea, and are now engaging in what appears to be pretty open attempts - some successful - at political assassination.
"It is not a new Cold War - it is a new something else - unpredictable and dangerous, fuelled by a Russia full of resentment and a sense of humiliation towards the West."
He continued: "We need to play to our strengths here and have a smart response.
"I don't think we have been so threatened since the mass expulsion of Soviet spies in 1971, when we threw out 105, because so great was the Soviet espionage operation in those days."
He added: "We are now in the 21st century, we have moved on from then, but at the same time we have gone backwards to an area in relations where there are no proper rules."
