Theresa May calls for 'long-term response' to Russia after spy poisoning

British Prime Minister Theresa May called on Tuesday for a “long-term response” by the West to the security threat from Russia as NATO followed member states in expelling Russian diplomats over the poisoning of a double agent in England.

In the most sweeping such action against Moscow since the height of the Cold War, the United States and European Union members plan to expel scores of Russian diplomats in action against the Kremlin for the nerve agent attack on Sergei Skripal and his daughter which they have blamed on Russia.
