The premier of Germany's Thuringia state Thomas Kemmerich offered to resign Thursday, paving the way for snap polls, sources from his liberal FDP party said, a day after he was voted into office with help from far-right lawmakers. "Thomas Kemmerich wants to remove the stain of the AfD's support from the office of the premiership," the FDP's Thuringia branch told sources. mfp/tgb/bp
