As a show of Soviet domination, sixteen prominent leaders of the Polish anti-Nazi underground were brought to trial in Moscow in June 1945. Their removal from the political scene precluded the possibility of a democratic transition called for by the Yalta agreements. The trial of the defendants, falsely and absurdly accused of collaboration with the Nazis, was watched by British and American diplomats without protest. The absence of the expected death sentences was their relief. The exiled government in London, after Mikołajczyk's resignation led by Tomasz Arciszewski, ceased to be officially recognized by Great Britain and the United States on 5 July 1945.
