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. (TV: The Invasion of Time)

Assignments
The Chancellor was secretly entrusted with holding the Great Key of Rassilon. (TV: The Invasion of Time)

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.
