Senegalese opposition figure Ousmane Sonko's presidential plans have been blighted by a fresh barrage of criminal charges and the dissolution of his party ahead of next February's elections."It is impossible for Ousmane Sonko to stand in the presidential election", political analyst Abdou Ndukur Kacc Ndao told AFP. He said Sonko's PASTEF party does not have the political means necessary for Sonko to run.
