A British-American national, Andrew Wilson, has presented to court a collection of devices he says he used to secretly record meetings involving veteran opposition politician Dr Kizza Besigye and his associate Joel Wakayima in a case related to allegations of plotting to overthrow the government.

Wilson appeared before court and displayed what he described as hidden recording gadgets, including power banks, watches and other items allegedly fitted with cameras and audio recording technology.

While giving evidence, Wilson told court that he captured meetings held in Geneva, Switzerland; Athens, Greece; and Nairobi, Kenya, using devices disguised as ordinary personal and household items.

The witness said the recordings were made during meetings he attended with Besigye and Wakayima, claiming that the devices allowed him to secretly collect both audio and visual information.

While being led through his testimony by prosecutor Richard Birivumbuka, Wilson presented a covert camera disguised as a wall USB charger.

He told court that the charger-shaped camera was used during a meeting in Geneva, where he also allegedly used another audio recording device placed on a steel radiator.

Wilson further presented a small recording gadget, explaining how it was positioned during the meeting to capture conversations without attracting attention.

During another meeting, the witness said he used a disguised power bank containing a hidden camera that was placed on the meeting table.

He explained that the device appeared like an ordinary power bank but had been modified to record events taking place around it.

Wilson also told court that he used specially designed watches fitted with hidden cameras during a meeting in Athens.

According to his testimony, one of the watches was worn by an associate who sat across from him at the table while the recording was taking place.

The witness also presented an audio recording device disguised as a necklace, which he said he wore around his neck while attending the meetings.

Describing the gadget before court, Wilson said it looked like a teardrop-shaped item with an opening used for charging and retrieving recorded information.

He told court that some of the recorded material was later transferred to a power bank for storage.

Wilson explained that he moved the information because he travelled frequently and did not want to carry material that could suggest involvement in alleged plans to overthrow the government or activities involving illegal currency.

“I needed to transfer the information because I travel a lot, and I didn’t want to be found with material that suggested plans to overthrow the government or dealings in illegal currency,” Wilson told court.

The witness presented the devices ahead of a session where he is expected to play the audio and video recordings he says were captured during the meetings.

However, during his testimony, Wilson could not identify the manufacturers of the devices he presented to court.

He instead described the equipment based on its appearance and the purpose he said it served during the alleged recordings.

Wilson also presented two mobile phones to court, saying he used them to communicate with Dr Besigye and Wakayima.

The evidence presented by Wilson is expected to form part of the prosecution’s case as court continues hearing allegations surrounding the alleged plot against the government.

Dr Kizza Besigye, a longtime opposition leader and former presidential candidate, has denied wrongdoing, while his supporters have described the case as politically motivated.

The court proceedings continue as prosecutors present their evidence and the defence team challenges the allegations brought against the opposition figures.
