It's unacceptable to give Chishimba Kambwili harsh treatment, says Vincent Chaile, president of the opposition Radical Revolutionary.
Chaile says one does not need to be a rocket scientist to know that the charges levelled against Kambwili were fake.
"Ancient politics of intimidation is long gone and can never be entertained in this era...
"The ruling PF should know that politics is about ideas and sharing ideas and not about using state institutions to suffocate certain voices," said Chaile.
The former UNZASU president says critics of a sitting government are part of good governance in a democracy.
"A good leader must be able to embrace different views... especially from his opponents. Sending opposition leaders to prison for trumped up charges will not bring food or pay rentals for Zambian people," he said.
Chaile urged the PF government to learn from the MMD and avoid being brutal to the opposition.
