[1] Diallo resigned from the CDP in January 2014 and participated in the founding of an opposition party, the People's Movement for Progress (MPP), becoming its First Vice-President.

Diallo, who was born in Ouahigouya, Yatenga Province,[1] was expelled from the University of Ouagadougou for having organized strikes and protests.

He then belonged to the Voltaic Revolutionary Communist Party and went on to Dakar, Senegal, to continue his Master of Law studies there.

In 1985 he returned to Burkina Faso and joined the dissident and pro-Sankara splinter-faction of the PCRV, the Burkinabé Communist Group.

Those who resigned said that the party was being run in an undemocratic and damaging manner, and they expressed opposition to plans to amend the constitution to eliminate term limits, which would allow President Blaise Compaoré to stand for re-election in 2015.

[9] A new opposition party led by the prominent CDP members who resigned, the People's Movement for Progress (MPP), was founded on 25 January 2014.
