Two Russians are due to go on trial in Angola accused of stirring up anti-government protests, conducting a campaign of disinformation, and attempting to interfere in next year's presidential election.

Arrested last August, political consultant Igor Ratchin and translator Lev Lakshtanov are facing 11 charges, including terrorism, espionage and influence peddling.

The BBC has obtained a copy of the indictment that includes charges relating to an alleged operation aimed at changing the political course of Angola.

The Russians' lawyers challenge the indictment on the grounds that it lacks "concrete and objective facts".

According to the prosecution, the Russians acted on behalf of Africa Politology, a shadowy network of operatives and intelligence officers in Africa that emerged from the now-defunct Wagner Group, whose founder Yevgeny Prigozhin died in 2023 in a plane crash.
