President of the High Council

The Lord President or Lady President (or President of the Council or simply President) governed the High Council of Time Lords, making him or her the holder of the most powerful office on Gallifrey.

According to Lady President Romana, the full, formal and legal title of the position was: President of the Supreme Council of Gallifrey and All Her Dominions, Holder of the Wisdom of Rassilon, Preserver of the Matrix, Guardian of the Legacy of Omega. (AUDIO: The Inquiry)

The ceremonial privileges of the President included access to the APC Net by means of the Matrix Crown (TV: The Invasion of Time) and the possession of the Sash and Rod of Rassilon. (TV: The Deadly Assassin)

The President also had the formal responsibility, not attempted in reality except by the Fourth Doctor, to seek the Great Key of Rassilon - a separate artefact from the Rod of Rassilon, which was also sometimes referred to as the Key of Rassilon. (TV: The Invasion of Time)

The Lord President could not be put on trial, (TV: The Mysterious Planet) but he or she could certainly be called to give evidence in a judicial investigation. (AUDIO: The Inquiry)

Different incarnations of the same Time Lord can be a different number President, as shown by the Doctor being the 407th and 409th president. This is possible as when Romana's presidency was impeached and she was nearly deposed, in her present incarnation she wasn't permitted to contest the presidency against Inquisitor Darkel and Lord Cardinal Mathias, however she said she would go under voluntary regeneration and contest it in her next incarnation. This didn't happen as she wasn't deposed. (AUDIO: Appropriation)

Alternative timelines

 * In an alternative timeline, the Doctor became Lord President and led the Time Lords in a war against the Daleks, who were being aided and abetted by the Master. (PROSE: The Quantum Archangel)
 * In a timeline in which it was standard policy for the Time Lords to sell their temporal technology to the highest bidder and regenerations could be extracted and sold, Leela and K9 Mark I accompanied the Fourth Doctor on his search for the Key to Time. She was the only human to hold the Key to Time in her hands. Consequently, when Leela's counterpart from the proper timeline visited this alternative Gallifrey, she was appointed Lady President. (AUDIO: Reborn)
 * In a timeline in which the Time Lords regularly altered history through the Temporal Intervention Agency, Romana became Lady President as in the proper timeline but was considerably more ruthless than her counterpart. Her Interrogator General was Leela, who murdered her predecessor Narvin to achieve the position, while the Doctor, by then in his sixth incarnation, served as Lord Burner, the President's personal temporal assassin who "burned" people from history. Vansell served as Castellan. (AUDIO: Disassembled)
 * In a timeline in which Rassilon failed to finish the Eye of Harmony before his death, Romana reigned as Lady President over a Gallifrey which never achieved time travel and where slavery still existed. She was assassinated on the orders of Lord Chancellor Narvin but was immediately replaced by her counterpart from the proper timeline, who claimed that the victim of the assassination was a decoy. After the alternative Narvin was killed by the Krilig, the Narvin from the proper timeline assumed his identity. (AUDIO: Forever)
