Michael Müller (politician, born 1964)

In parliament, Müller has been serving on the Committee on Foreign Affairs (since 2021) and its Subcommittee on Foreign Cultural and Educational Policy (since 2022). He has also been chairing a study commission set up to investigate the entire period of German involvement in Afghanistan from 2001 to 2021 and to draw lessons for foreign and security policy in future.

In August 2020, Müller announced his intention to leave state politics and instead run as a candidate in the 2021 national elections. In the negotiations to form a so-called traffic light coalition of the SPD, the Green Party and the Free Democrats (FDP) on the national level following the elections, he was part of his party's delegation in the working group on innovation and research, co-chaired by Thomas Losse-Müller, Katharina Fegebank and Lydia Hüskens.

He was also President of the Bundesrat from November 2017 until October 2018, which made him deputy to the President of Germany.

Müller had previously made a surprise entry into the race to succeed Wowereit and defeated two candidates initially seen as the most likely successors. Shortly before the election, Müller ran for the Leadership of the Social Democratic Party in Berlin a second time, and won. In the 2016 Berlin Election, he led the party to victory, albeit not without some losses. After the election, Müller ended the grand coalition with the Christian Democratic Union and formed a new government with the Green Party and the left-wing Die Linke.

In December 2014, Müller took over in midterm from the incumbent Klaus Wowereit, Berlin's longest-serving mayor since reunification in 1990, who presided over the city's emergence as a popular tourist destination and center for high-tech start-ups but stepped down after his popularity suffered from the debacle around the Berlin Brandenburg Airport.

As one of the state's representatives at the Bundesrat, Müller served on the Committee on Foreign Affairs, the Committee on European Affairs and the Committee on Cultural Affairs from 2014.

Following the 2011 state elections in Berlin, Müller was senator for urban development and the environment from 1 December 2011 to 11 December 2014. One of his most extensive projects, which planned to build business space and apartments on the grounds of the former Tempelhof Airport, was rejected in 2014 by a clear majority of Berlin citizens in a referendum.

Müller was an SPD delegate to the Federal Convention for the purpose of electing the President of Germany in 2004, 2009 and 2012. In the negotiations to form a coalition government under the leadership of Chancellor Angela Merkel following the 2017 federal elections, he was part of the working group on urban development, led by Bernd Althusmann, Kurt Gribl and Natascha Kohnen.

Müller was elected to the Berlin House of Representatives in 1996 and has been a member ever since. On 16 June 2001, he took over leadership of the SPD Group in the House of Representatives from Klaus Wowereit who had been elected Governing Mayor of Berlin. After the resignation of Peter Strieder in April 2004, Müller ran for the Berlin SPD State Party Leadership and won, remaining the Leader of Berlin SPD until he lost his re-election bid against Jan Stöß in June 2012.

Rainer Michael Müller (born 9 December 1964) is a German politician of the Social Democratic Party (SPD) who served as Governing Mayor of Berlin from 2014 to 2021 as a member of the German Bundestag since the 2021 elections, representing the Berlin-Charlottenburg-Wilmersdorf district.
