WATCH: Outgoing @Twaweza_NiSisi Executive Director @aeyakuze recounts the challenging period when the Tanzanian government confiscated his passport over a citizenship inquiry. 

This occurred after Twaweza published a citizen survey report revealing a decline in President John Magufuli's popularity.

He describes it as a profoundly difficult situation that posed a serious threat to Twaweza's very existence.

The Court of Appeal ordered the government to close the investigation and return Eyakuze's passport. 

"We did not falter from standing up for the things we felt were absolutely fundamental and non-negotiable. Freedom of expression for Twaweza is non-negotiable," he said.
