The communists refused to deal with the Underground State just like they refused to deal with the government in exile; its leaders and soldiers in "liberated" Polish territories were persecuted. A number of prominent leaders of the Underground State, including the Government Delegate, Jan Stanisław Jankowski and the last AK Commander-in-Chief, General Leopold Okulicki, who decided to reveal themselves and upon the Soviet invitation begun open negotiations with the communist authorities, were arrested and sentenced by the Soviets in Moscow in the infamous Trial of the Sixteen (arrests were carried out in March 1945, and the trial itself took place in June that year). On 27 June 1945 the Council of National Unity held its last session, issuing a 12-point declaration demanding that the Soviet army leave Poland and the repression of the non-communist political parties cease. The Government Delegate's Office at Home, restructured after the arrests of its leadership and headed by the last Delegate, Stefan Korboński, disbanded on 1 July, after the creation in Moscow of the Provisional Government of National Unity (Tymczasowy Rząd Jedności Narodowej, TRJN) on 28 June 1945. The disbanding of those structures marked the end of the Underground State.
