The Provisional Government of National Unity was a provisional government formed by the decree of the State National Council 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 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 the fait accompli of Poland tacitly becoming part of the Soviet sphere of influence, and to legitimise the Warsaw government while withdrawing their recognition of the Polish government-in-exile. The puppet government became known as the "Lublin Committee" or the "Lublin Poles" or the "Lublin Government", and it garnered the recognition of all Allied governments at the time.
