However, with newly restored independence, the country's government instead concentrated on shoring up good relations with traditional ally France, and immediate neighbour Germany.

The government also signed a three-way mutual defence pact with the United Kingdom and France with the original intent being to make sure an independent and sovereign, democratic Poland would never again have to stand alone against a German invasion.

Then, immediately after World War II, when Poland (1945–1989) was forced to become a satellite state of the Soviet Union due to Soviet takeover and decisions made on behalf of Poland without representatives present at the Yalta Conference, the British government suddenly refused to recognise the government in exile[3] and thus the London Poles (Officials of the Polish government in exile, now from their own embassy building – as they were referred to) were forced to vacate the Polish embassy on Portland Place and so, were left only with the president-in-exile's private residence at 43 Eaton Place, whilst in the meantime officials of the newly recognized communist regime moved squarely into the original Georgian-era embassy building.

It wasn't until the fall of Communism, the Soviet Union, the Berlin Wall, the end of the Polish United Workers' Party, and the re-establishment of democratic rule under President Lech Wałęsa in 1990, that the embassy at 47 Portland Place was vacated once again; this time of the communist regime in 1989, to once again become the official seat of the primary diplomatic legation of the original Polish Republic to the United Kingdom.

It was here in the Polish Embassy in London that the initial processes to repatriate the official presidential seal and symbols of office (which had previously been evacuated to London with the government in exile at the beginning, and for the duration, of World War II and all of the years of Soviet influence) to finally re-establish in 1990 a free and democratic Poland to the Polish people living in Poland.
