The Syndicate was a criminal group active in the 41st century that was composed of the surviving members and heirs of the representatives of the Outer Galaxies on the Galactic Council who joined the Daleks in their Great Alliance in 4000, (TV: The Daleks' Master Plan) although they denied Zephon membership. (AUDIO: Time's Assassin)
The Syndicate was formed to control Earth and get revenge on the Fourth Doctor, (AUDIO: The Perfect Prisoners) and controlled lesser criminal groups such as the Sinestrans and Lemurans. (AUDIO: The Sinestran Kill) Acting as a sleeper Time Agent, Anya Kingdom systematically eliminated nearly every member of the Syndicate. (AUDIO: The Perfect Prisoners)
