ST JOHN’S, Antigua – The leader of the United Progressive Party (UPP), Baldwin Spencer, will not be challenged for the post at the party’s convention on Sunday. A document listing the 14 positions up for grabs shows Spencer as the lone candidate vying for the position, while Leon “Chaku” Symister is the only contestant seeking to fill the post of chairman. Current chairman and Deputy Political Leader Harold Lovell, said Spencer has his “unequivocal” support.
