Senior BNP leader Barrister Moudud Ahmed said they will wage a “harsher movement in due course” to oust the current government.
"They [government] have no future. Their fall will come soon. Have patience and wait for that day," he said.
Speaking at a discussion on Saturday, Moudud further said: "A tougher movement will be waged in due course as we know it is not possible to oust a fascist and autocratic regime with peaceful programs."
Nagorik Odhikar Andolon arranged the discussion at national Press Club in Dhaka, protesting the ongoing extrajudicial killings on the pretext of gunfights.
Moudud, a BNP Standing Committee member, said the forthcoming general elections must be held under a nonpartisan government.
"The constitution is not above the people... It can be amended as per the people's will. The constitution will not be an obstacle to holding a free, fair election under a non-party administration."
He alleged that the government was harassing and arresting BNP leaders and activists in the name of anti-narcotic drives.
"The anti-narcotic operation is being carried out to eliminate opposition forces. We demand such unjustified actions be stopped immediately.” the BNP leader added.
He alleged that law enforcement agencies were extorting money from people by threatening them to implicate in “false” drug-related cases.
Moudud said their chairperson, Khaleda Zia, was seriously ill, as she has been kept in an abandoned and damp jail.
He demanded the government immediately ensures she gets proper treatment at a specialized hospital.
