Poland's lower-house Speaker Szymon Hołownia said on Friday that he wanted Morawiecki to present the new Cabinet to parliament for approval as soon as possible.
Earlier in the day, Morawiecki said he would unveil the lineup of his new government on Monday, adding that it would be a "cross-party coalition for Poland."
Speaking to reporters on Friday, Hołownia said that Monday would mark "the end of the 14-day constitutional deadline" for Morawiecki to unveil the Cabinet.
He added that President Andrzej Duda was likely to swear in Morawiecki's Cabinet on Monday, Polish state news agency PAP reported.
Hołownia said at a news conference in the northeastern city of Białystok that he expected to meet with Morawiecki next week and that he would urge the prime minister-designate "to present the new Cabinet to parliament as soon as possible."
Hołownia, who leads the centre-right opposition Poland 2050 grouping, told reporters that he would "invite Prime Minister Morawiecki for talks as soon as the Cabinet is appointed."
He added that the meeting could take place on Wednesday or "on some other suitable date next week."
Hołownia noted that Morawiecki would have 14 days to "present his ministerial team to MPs."
Morawiecki declared on Friday that strengthening Poland's security would be a priority for the new Cabinet, and that spending on defence should reach 4 percent of GDP.
Morawiecki added that his new Cabinet would oppose changes to European Union treaties, such as transferring defence policy powers from member states to Brussels.
He told reporters that his new government would enact "green-friendly policies," such as new projects in photovoltaics, thermal overhaul of public facilities and expansion of biogas plants, while also making efforts to protect Poland's national heritage.
'No chance' of team-up: Far-right leader
Meanwhile, Morawiecki met with politicians from the far-right Confederation group on Friday to discuss the formation of the new Cabinet, public broadcaster Polish Radio's IAR news agency reported.
Earlier, MPs from the Left party and the Third Way alliance, which comprises Poland 2050 and the rural-based Polish People's Party (PSL), declined his invitation for talks on the new government, according to news outlets.
After Friday's meeting, Confederation's Krzysztof Bosak, a deputy lower-house Speaker, said there was "no chance" of his party teaming up with Morawiecki's Law and Justice (PiS) to govern jointly, the PAP news agency reported.
Bosak added that Confederation had a "critical view" of Morawiecki's "current government policies."
Bosak said the talks with Morawiecki had focused mainly on issues such as the evacuation of Poles from war-torn Gaza and an ongoing protest by Polish transport companies at the Ukrainian border, the PAP news agency reported.
Poland to appoint new gov't
Poles elected a new set of 460 MPs and 100 senators when they went to the ballot box last month.
The Polish president this month named Morawiecki, who has led Poland's government since 2017, as prime minister-designate, tasking him with forming a new Cabinet.
The ruling conservative Law and Justice party won Poland's October 15 election, but lost its parliamentary majority and looks unlikely to stay in power for a third consecutive term.
Meanwhile, opposition leader Donald Tusk has already chosen most candidates for ministerial roles in his future Cabinet, according to the Rzeczpospolita newspaper.
Hołownia told reporters on Friday that "all the names of the members of Donald Tusk's future government have been agreed on," the PAP news agency reported.
A bloc of opposition parties led by Tusk's Civic Coalition last week secured a resounding victory in Poland's new parliament during its first key vote to elect a house Speaker.
On November 10, these opposition groups, which also include the rural-based Polish People's Party (PSL), the centre-right Poland 2050 group and the Left party, signed an agreement to form a coalition government, pledging to restore the rule of law, promote green energy and relax abortion rules, among other policies.
Tusk was Poland's prime minister from 2007 to 2014.
