Senegalese Democratic Party
The party was born through a split from the Senegalese Democratic Party (PDS). Ngom resigned from the PDS on June 11, 1998, after the party leadership was rearranged by PDS Secretary-General Abdoulaye Wade on June 5 and Ngom lost his position as deputy leader of the party and became permanent secretary instead. Ngom announced the creation of the PLS on June 18.
