The official campaign period for the referendum was scheduled to run from 9 October to 23 October 2015. Speaking at the beginning of the campaign period,
Raymond Mboulou, the Minister of the Interior, stressed the importance of campaigning being conducted "in a climate of social peace, a climate of tolerance, of acceptance of different opinions, a climate that excludes provocations ... and which fundamentally preserves the public order." A large rally in support of the referendum was held in Brazzaville on 10 October. Speaking at the rally, the Secretary-General of the
Congolese Party of Labour (PCT),
Pierre Ngolo, declared that "this human tide simply wants to say that changing the constitution is the will of the people, and as such no one can stop it." A protest against the referendum was held in Brazzaville on 20 October. The demonstration had been banned by the government and was dispersed by police. Protesters set up barricades in the streets and attacked police stations. Police fired into the air and used tear gas to break up the protest, and four people were reportedly shot and killed by police during the violence. Protests continued for a second day in the
Makélékélé section of Brazzaville on 21 October, with the protesters again setting up barricades and
burning tires. The army was called in and helped police disperse the protesters. Hardline opponents of the referendum planned to boycott the vote, viewing it as nothing more than a way for Sassou Nguesso to remain in power, and said they would continue protesting. Ngolo, on the other hand, argued that it was necessary to change the constitution "for the future of the country, to ensure peace and stability". Meanwhile,
François Hollande, the President of
France, said that "Sassou can consult his people. That's part of his right and the people must respond." ==Conduct==
