A new Prime Minister has been elected in North Rhine-Westphalia just seven months before the state elections.
The CDU politician Hendrik Wüst received 103 votes and thus the required majority.
The state parliament met for a special session this Wednesday to vote on Laschet's successor.
The 46-year-old lawyer from the Münsterland went to the election as a joint candidate of the government factions of the CDU and FDP.
The failed Union Chancellor candidate Laschet has been a member of parliament in Berlin since the constituent session of the Bundestag on Tuesday. Laschet had ruled out a return to North Rhine-Westphalia regardless of the outcome of the federal election. On Saturday, Wüst had already been elected as the new CDU state chairman at a party conference. He succeeds Laschet in this position as well.
Before the vote, Laschet was officially adopted in the state parliament.
He had already resigned from the state parliament president on Monday.
According to the state constitution, a member of the NRW state government cannot be a member of the Bundestag at the same time.
With the meeting of the Bundestag on Tuesday, Laschet's executive office also ended.
His deputy, Family Minister Joachim Stamp (FDP), temporarily took over the management of government affairs.
As a member of the state parliament, Laschet Wüst can and wants to vote on Wednesday.
Laschet is probably only a member of the state parliament and the Bundestag for a short time.
