The Party’s general secretariat members said they were resigning including its leader Saad Dine El Otmani.
The party is in disarray after it came eighth in general elections with only 13 in the 395-seat parliament, in what many describe as a punishment for the party by Morocco’s electorate.
However, the party fell short of upholding democratic practices by directing accusations to election authorities and rivals and blaming their resounding defeat on violations instead of looking within.
The final results showed an increase in the number of seats won by the RNI to 102, followed by PAM 86, the PI 81, USFP 35, MP 29, PPS 21 and UC 18.
Turnout increased to 50.35% with 8.78 million Moroccans casting ballot, compared with 42% in 2016.
