The Provisional Government of National Unity (Polish: Tymczasowy Rząd Jedności Narodowej, TRJN) was a puppet government formed by the decree of the State National Council (Krajowa Rada Narodowa, KRN) on 28 June 1945 as a result of reshuffling the Soviet-backed Provisional Government of the Republic of Poland established by the Polish Workers' Party (Polska Partia Robotnicza, PPR) through inclusion of politicians from the close political sphere of Stanisław Mikołajczyk, the former prime minister of the Polish government-in-exile based in London. Inclusion of the latter group provided an excuse for the Western allies to approve tacitly the fait accompli of Poland becoming part of the Soviet sphere of influence, and to legitimise the Warsaw government while withdrawing their recognition of the Polish government-in-exile.
