Workers' Volunteer Battalions. After the German and Soviet take-over of Poland he went underground and, together with Kazimierz Pużak, on 16 October of the same year he proclaimed the Polish Socialist Party – Freedom, Equality, Independence (PPS-WRN), a secret war-time continuation of the pre-war PPS. He headed that party until July 1944. After that he entered the Council of National Unity (RJN), a quasi-parliament of the Polish Secret State headed by Jan Stanisław Jankowski. Shortly before the outbreak of the Warsaw Uprising, Arciszewski was evacuated from Poland through an air bridge (Most III) on 26 July 1944. Through Cairo he reached London, where he was one of the candidates for the seat of the president of Poland in exile. In accordance with the April Constitution of 1935, on 7 August 1944 he was named by Władysław Raczkiewicz as his successor. Critical towards the pressure of the Soviet Union and Stanisław Mikołajczyk's attempts at compromise with Joseph Stalin, Arciszewski focused on trying to convince the Allied leaders (notably Winston Churchill) to help fighting Warsaw – to little avail. After Mikołajczyk's resignation, on 29 November 1944, Arciszewski became the Prime Minister of Poland and at the same time he became the minister of labour and welfare in his government. He died on 20 November 1955 at aged 78, and is buried in Brompton Cemetery, London.
