Deputy Prime Minister and Digital Affairs Minister Krzysztof Gawkowski said on Saturday that the party had achieved "a thousand things and a thousand changes" since entering government.
He cited pay rises for teachers, 15,000 births through IVF, 34,000 homes built under what he called the largest government housing programme in 30 years, and more than 730,000 laptops and tablets for schools.
He pointed to a widow's pension he said was used by a million people, and a higher funeral allowance.
He also listed the "Active Parent" programme, with a budget of PLN 10 billion (USD 2.6 billion), which he said had cut nursery prices tenfold.
Nearly 400 couples in Poland had so far registered marriages conlcuded abroad, he added.
Gawkowski said Poland "does not need to fear war" because it was spending record sums on defence.
He noted that Poland's economy was worth about USD 1 trillion and had grown ten times faster than Germany's in 2025.
He also criticised a statement posted by President Nawrocki's office on X saying Poland could lose territory but never its soul.
Gawkowski added that the government would not "give away one metre of Polish land" and called the president's words "treason."
Speaker of the Sejm Włodzimierz Czarzasty said the Left would not agree to changes to the constitution proposed by the president, and accused Nawrocki of wanting to be "king, speaker and prime minister."
"The right-wing state is strong against the weak and weak against the strong," he told the convention.
Senate Deputy Speaker Magdalena Biejat said the Left would keep pushing for legal, safe and accessible abortion
Family and Labour Minister Agnieszka Dziemianowicz-Bąk criticised the far-right Confederation party, saying it did not want workers to be paid decently.
