German economy minister vice chancellor and party chairman   Philipp Roesler gestures during a meeting of his Free Democratic Party (FDP) in Stuttgart, southern Germany, Sunday Jan. 6, 2013.  Germany's embattled vice chancellor is battling to quell speculation about his leadership of the country's junior governing party, whose dire poll ratings are a complicating factor in Chancellor Angela Merkel's bid for re-election.  Philipp Roesler, who's also Germany's economy minister, appealed to his pro-market Free Democratic Party on Sunday to show unity ahead of a state election in his home region of Lower Saxony on Jan. 20, an important political test ahead of national elections in September.
