Chief Officer

From Tardis Wiki, the free Doctor Who reference

The Chief Officer of Varos was in league with Sil to have the current Governor of Varos replaced with one who would agree to keep the prices of Zeiton-7 low. He tried to have the Sixth Doctor killed, but he and Quillam were themselves killed by deadly vines in the Punishment Dome. (DW: Vengeance on Varos)
