The oath-taking ceremony of the newly elected members of parliament will take place on Tuesday, reports bdnews24.com.
Parliament Secretariat Secretary Kaniz Moul confirmed the date on Saturday.
Another official said the new government may take oath the same day.
Buoyed by a decisive mandate, the BNP is set to return to power after two decades.
Emerging from 17 years of self-imposed exile in the UK, Tarique Rahman has led the party to an absolute majority in a historic election - the first in Bangladesh held without the Awami League, which was barred from contesting in the aftermath of the 2024 Uprising.
Parliamentary polls were held on Thursday across 299 constituencies, with results declared in 297 seats.
The BNP emerged dominant, winning 209 seats. Its former ally, the Jamaat-e-Islami, secured 68 seats, positioning itself as the principal opposition force in the new parliament.
Late on Friday night, Election Commission Secretary Akhtar Ahmed published the official gazette naming the 297 elected lawmakers. The EC also published the results of the referendum on reform proposals.
Even as the formalities move forward, uncertainty persists over who will administer the oath to the newly elected MPs, as the speaker of the outgoing parliament, Shirin Sharmin Chaudhury, remains out of public view.
Amid the discussion, former Cabinet Secretary Sheikh Abdur Rashid said on Saturday that, under the Constitution, the president will administer the oath of office to the cabinet.
Speaking to reporters at his Secretariat office earlier in the day, he said that in the absence of a speaker or deputy speaker, the chief justice or the chief election commissioner is also constitutionally empowered to swear in members of parliament.
Following the parliamentary elections in 2024, Shirin Sharmin assumed office as speaker when the Awami League formed the government. She is now facing cases.
The then deputy speaker Shamsul Haque Tuku, who is also a suspect in multiple cases, is currently in jail, creating a procedural complication over the administration of oaths for the new MPs.
Asked about the timeline, the cabinet secretary said the gazette notification had already been issued and that, under the law, lawmakers must take their oaths within three days.
"That three-day period will begin tomorrow and [MPs] must take oath by the 17th [of February]," he said.
He added that once the oath process is completed, the parties represented in parliament will select their respective parliamentary leaders.
The leader chosen by the majority will then formally inform the president that he commands the confidence of the majority of members.
