High Chancellor

Lord or Lady Chancellor (Chancellor for short) was an office of the High Council of Time Lords.

Rank
The Chancellor was next in rank to the Vice President, and so third in the overall hierarchy. As there often was no Vice President, the Chancellor would rank directly below the Lord President.

Assignments
The Chancellor was secretly entrusted with holding the Great Key or Key of Rassilon. (TV: The Invasion of Time) It appears that the Chancellor had authority over the Castellan and therefore the Chancellery Guard. The Chancellor also appears to have had overall control of the Time Lord Academy. (AUDIO: Insurgency)

Appointment
The appointment of the Chancellor was in the hands of the President. (AUDIO: Pandora) However, during the sede vacante of the Fourth Doctor as a President elect, not yet invested, the High Council ratified the appointment of Borusa as Chancellor. (TV: The Invasion of Time) In another occurrence, President Romana allowed the Council to appoint Valyes acting Chancellor after Braxiatel was removed from office. (AUDIO: Insurgency)''

Other information
Narvin regarded the chancellorship as being "the worst job on Gallifrey." (AUDIO: Forever)

By the time of the run-up to the Second War in Heaven, there appeared to be four Chancellors: the Chancellor of Time Past, the Chancellor of Time Present, the Chancellor of Time Parallel and the Chancellor of Time Future. (PROSE: The Ancestor Cell)
