The U.K. is sharing secret intelligence about the nerve agent attack on a former spy with key allies, in an effort to persuade them to expel Russian diplomats across Europe, people familiar with the matter said.
Prime Minister Theresa May ordered 23 Russian operatives -- who she said were undeclared spies -- to leave Britain last week in retaliation for the attack on Sergei and Yulia Skripal in Salisbury, England. Now she wants other countries to follow Britain’s example, condemning Russia and taking action against Kremlin agents, according to the people, who asked not to be named discussing sensitive security matters.
