CORRECTION-GERMANY-POLITICS-PARTY-CONGRESS-CDU

German Chancellor Angela Merkel shakes hands with Ukrainian box champion and member of Ukrainian Parliament Vitali Klitschko during a congress of Germany's ruling conservative Christian Democratic Union (CDU) party on December 4, 2012 in Hanover, central Germany. German Chancellor Angela Merkel was re-elected head of her conservative Christian Democrats (CDU) by more than 97 percent of delegates' votes at a two-day party congress. It was Merkel's best result since she took over as chairman of the CDU in 2000 and comes as she gears up for fighting for a third term at the helm of Europe's top economy in elections expected in September 2013.
