Kelner

Kelner served as Castellan of Gallifrey at the time ofThe Doctor's return to Gallifrey to assume the office of President. Unlike his predecessor Spandrell Kelner appeared to by much more of a politician and ambitious. After the Vardan invasion he assisted the Doctor to remove Time Lords who might oppose the new regime, drawing up lists of those who he had a persoanl grudge against, such as Surgeon General Gomer. At this point he was told by the Doctor to consider himself as acting Vice President. Andred disliked him but stayed in post because he thought he might be able to lead a resistance movement within the Capitol and act as a foil to the corrupt castellan.

Kelner was equally at home collaborating with the Sontarans who had used the Vardans as a cat's paw to their own invasion.

Kelner's ultimate fate is unknown, but it is unlikely that he remained in office after the invasion was defeated through the use of the DEMAT Gun. (DW: The Invasion of Time)
