Career
He has been Governing Mayor of Berlin since 11 December 2014. Müller was a Social Democratic Party of Germany delegate to the Federal Convention for the purpose of electing the President of Germany in 2004, 2009 and 2012. Following the 2011 state elections in Berlin, Müller served as Senator for Urban Development and the Environment from 1 December 2011 to 11 December 2014.
His most extensive project were the plans to build business space and appartments on the former Tempelhof Airport, which were rejected in 2014 by a clear majority of the citizens of Berlin via referendum.
He was Chairman of the parliamentary group of the Social Democratic Party of Germany in the Abgeordnetenhaus of Berlin from June 2011 to November 2011 and State Chairman of the Social Democratic Party of Germany from 20 June 2004 to 9 June 2012. In December 2014, Müller took over in midterm from 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 startups but stepped down after his popularity suffered from the debacle around the Berlin Brandenburg Airport.
Müller had previously made a surprise entry into the race to succeed Wowereit and defeated two candidates initially seen as the most likely successors. Müller"s term will run until late 2016, when Berlin will hold new elections.
