Speaking at a discussion, he, however, said they will not need to go for a movement if the problems are resolved through talks.
"We'll hold our public rally at Suhrawardy Udyan the day after tomorrow (Tuesday) and announce action programmes from there for a bigger movement," Manna said while addressing a programme.
He said their programmes will be non-violent as there will have no arson, vandalism and terrorism in their movement.
Jatiya Manobadhikar Andolon arranged the programme at the Jatiya Press Club.
Manna accused the government of resorting to 'violence and killing, enforced disappearance and massive repressive acts to suppress' its opponents.
"I would like to say come to a good path shunning it (repressive acts)...if you think you'll take walkover like that of January-4, 2014, you're wrong as you'll have to face a very strong struggle this time," he warned.
Manna said the Oikyafront leaders want to hold talks with the Prime Minister with the list of fictitious and political cases.
The Nagorik Oikya convener said though the Prime Minister said there is no restriction on meetings and rallies, step was not taken to implement it as Oikyafront was not yet given permission to hold its rally in Rajshahi.
Referring to Prime Minister's remarks that Oikyafront is carrying out movement while the dialogue is going on, Manna said, "We didn't give any action programme. Rather, you're doing it as you're holding rallies by halting examinations, flyovers and bus communication."
Manna called upon the Election Commission not to announce the schedule for the next general election until the ongoing dialogue between the ruling and opposition parties is over.
