Lady Livia Caralis (Livia for short) of the House of Brightshore was a high ranking Time Lord. Despite being political opponents, President Romana II appointed her as her successor.

Biography
In the timeline where the Moros was destroyed, Plutus was Livia's ally and became her Castellan. Because she didn't trust Romana, Livia tried to recruit Irving Braxiatel to be her liaison and spy in the Celestial Intervention Agency. Time Lords from all across Gallifrey came to Livia's inauguration, but after the Monan Host embassy exploded and killed thousands, Livia announced an alliance with the Warpwrights of Phaidon and declared war on the Monan Host. However, Kalbez and Gaal later admitted in Livia's presence that they had framed the Monan Host; upon confronting Plutus for his part in the plot, Livia was kidnapped, but she was rescued by Leela and had Plutus arrested. After the timelines were rewritten, Livia was still named as Romana's successor, and she was inaugurated without incident. (AUDIO: Enemy Lines)

A different Lady President, who was eventually killed by the Sonomancer, was in office during Padrac schemes with the Doom Coalition. (AUDIO: The Eleven, Songs of Love)
