The UK must provide solid evidence of Russia’s alleged involvement in the Skripal case, the Czech president has said. While he did not oppose the country’s move to expel Russian diplomats, he believes it to be “a bit superfluous.” “I want to see the facts. I will certainly welcome if the United Kingdom presents some evidence that the Russians wanted to kill the double agent Skripal,” Czech President Milos Zeman told the Blesk news outlet on Tuesday.
