In an interview with public broadcaster Polish Radio, Jarosław Kaczyński said: “I believe this will happen directly after the holidays.”
He added that “there will certainly be personnel changes,” but, despite media speculation, Prime Minister Mateusz Morawiecki would keep his job as head of government.
“The prime minister will stay on, but the government will be restructured so as to eliminate a situation in which some decisions have to go through several different ministries,” Kaczyński told Polish Radio on Sunday.
He indicated that the bottom line was to make the decision-making process within the government less "dispersed" and more efficient.
Kaczyński, who heads Poland’s ruling conservative Law and Justice (PiS) party, did not name any Cabinet ministers who could be replaced.
Kaczyński’s party last fall secured a second term in power, together with two smaller right-wing groupings, in the wake of parliamentary elections.
Meanwhile, the country’s conservative President Andrzej Duda, an ally of the government, this month won a runoff vote and was re-elected for another five years as head of state.
