Klaus Wowereit

Klaus Wowereit (born 1 October 1953) is a German politician of the Social Democratic Party (SPD) and was the Governing Mayor of Berlin from 21 October 2001 to 11 December 2014. In 2001 state elections his party won a plurality of the votes, 29.7%. He served as President of the Bundesrat (the fourth highest office in Germany) in 2001/02. His SPD-led coalition was re-elected in the 2006 elections; after the 2011 elections the SPD's coalition partner changed from the Left to the Christian Democratic Union. He was also sometimes mentioned as a possible SPD candidate for the Chancellorship of Germany (''Kanzlerkandidatur''), but that never materialized. Provided by Wikipedia
