Britain is expelling 23 Russian diplomats after the nerve agent attack on a former Russian spy, the single biggest such expulsion since the Cold War.
Prime Minister Theresa May told the House of Commons on Wednesday that Russia has expressed ``disdain'' for Britain's wish for an explanation into the attempted murder of former spy Sergei Skripal and his daughter Yulia. She says that Russia's actions ``represent an unlawful use of force.''
May said the Russian diplomats have a week to leave Britain.
She also announced a range of economic and diplomatic measures, including a decision to cancel all high-level bilateral contacts with Russia and to ask the royal family not attend the soccer World Cup in Russia.
Russia has denied responsibility in the March 4 attack on the Skripals.
