Opponents of Serbia's President Aleksandar Vucic rallied outside the Constitutional Court building on Friday to press their demand that last month's election be annulled and held again over reported widespread irregularities. The Serbia Against Violence group has accused Vucic's populist government of orchestrating a fraud in the Dec. 17 parliamentary and local voting, particularly in the capital Belgrade. The state election commission has declared Vucic's Serbian Progressive Party the election winner and rejected the opposition's complaints.
