The original election date was chosen on 1 December 2016 after a meeting between the
President of Senegal Macky Sall and the Opposition in the
National Assembly. The coalition of parties supporting President Sall, Benno Bokk Yaakaar, sought to retain the parliamentary majority it obtained in the
2012 parliamentary election. It included Sall's party, the
Alliance for the Republic, as well as the
Socialist Party and the
Alliance of the Forces of Progress. Plans for a united opposition coalition that would incorporate the
Senegalese Democratic Party of
Abdoulaye Wade as well as the supporters of imprisoned
Dakar Mayor
Khalifa Sall were ultimately scuttled in late May 2017 because the two sides could not agree on who should head the coalition's candidate list. Consequently the two sides decided to stand separately, with Wade and Khalifa Sall each heading their respective lists. The opposition's failure to unite was viewed as a boon for President Sall, making it appear more likely that he would keep his parliamentary majority; if his supporters lost, he would be forced into
cohabitation for the remaining two years of his term, greatly curtailing his powers. ==Electoral system==
