According to dpa information, Armin Laschet (CDU) wants to submit his resignation as prime minister to the state parliament president on Monday morning and receive the certificate of discharge.
The "Bild" newspaper had previously reported.
Afterwards, Laschet would like to personally hand over their dismissal certificates to his ministers according to dpa information.
Düsseldorf - Laschet and State Parliament President André Kuper have to record and sign the request to resign.
After that, the outgoing Prime Minister should receive his certificate of discharge.
The other cabinet members, who were also dismissed along with their head of government - in accordance with the legal requirements - remain in office.
The new Prime Minister appoints his own cabinet after his election.
Laschet also remains in office until he becomes a member of the Bundestag on Tuesday morning.
At this moment, according to the state constitution, he can no longer be prime minister.
His deputy, Family Minister Joachim Stamp (FDP), takes over.
However, Stamp will only head the government for one day - according to current plans, Transport Minister Hendrik Wüst (CDU) will be elected as the new Prime Minister in a special session of the state parliament on Wednesday.
Curious: On this day, according to a parliamentary group spokesman, Armin Laschet will still be a member of the CDU in the state parliament - although he will also be a member of the Bundestag from Tuesday.
The state constitution allows this. Laschet can still vote for his successor Wüst.
Shortly afterwards, Laschet will - as one expects in the parliamentary group - resign from his state parliament mandate and only sit in the Bundestag.
