Foreign Secretary Jeremy Hunt has used a Sky News interview to tell Russia “the price will be too high” if it continues to act against international norms.
Mr Hunt suggested Moscow will be wondering whether the Salisbury chemical weapons attack was “a smart thing to do”.
Speaking to The Kay Burley Show in New York, he revealed his “frank exchange of views” with Russian counterpart Sergei Lavrov, during a “pretty tough” meeting at the UN General Assembly.
