President Andrzej Duda announced the meeting last week, after the new government under Prime Minister Donald Tusk was sworn into office.
The National Security Council was set to convene at 11:30 a.m. in Warsaw's Belweder palace, state news agency PAP reported.
The head of state invited the prime minister, the ministers of defence, foreign affairs, interior, security services and state assets, the Speakers of both houses of parliament, the leaders of parliamentary caucuses and the chief of the General Staff of the Polish Army, according to officials.
Talks were set to focus on "developments in Ukraine, including ways to further support Ukraine's defence against the Russian invasion," reporters were told.
Another topic would be Duda's plan to "reform the command and control system of the Polish armed forces," as part of a presidential bill on "measures to be taken by state agencies in the event of an external threat to national security," the PAP news agency reported.
The president was set to meet reporters after the closed-door meeting, on Wednesday afternoon.
Poland's National Security Council is tasked to advise the president on matters of the country's national and external security, according to officials.
It includes the prime minister, senior Cabinet members, top lawmakers, the heads of parliamentary groups and senior presidential officials, the PAP news agency reported.
Wednesday is day 665 of Russia’s war on Ukraine.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
