The party of Luxembourg\'s veteran Prime Minister Jean-Claude Juncker came out top in elections Sunday, initial estimates showed, but Europe\'s longest-serving leader lost ground to other parties. Juncker\'s conservative CSV party won 33.4 percent of the vote, according to RTL television, and 23 seats in the 60-seat parliament. This compared to 38 percent and 26 seats it won at the last election in 2009.
