Lubliner Komitee
In July 1944 Wasilewska became deputy chief of the Polish Committee of National Liberation (PKWN), a provisional government sponsored by the Soviet Union and established in Lublin, in opposition to the Polish government-in-exile in London. On 6–7 August, together with Bolesław Bierut and Michał Rola-Żymierski, Wasilewska conducted in Moscow unsuccessful negotiations with Prime Minister Stanisław Mikołajczyk of the government-in-exile (he refused their offer of becoming prime minister of a communist-dominated government).
