Walter Vincent

From Tardis Wiki, the free Doctor Who reference

Walter Vincent was the Grand Administrator of Earth. The Eighth Doctor and Narvin initially thought he was the Reborn Master, but he was in fact a construct, created from Molly O'Sullivan's memory of her father Patrick O'Sullivan. He got everyone to obey the Master. He called Molly "Molly Dark Eyes". The Doctor transmitted the retro-genitor particle through him to destroy the Eminence. (AUDIO: Rule of the Eminence)

He had a residence in Brunei, where he made an address from following the apparent defeat of the Eminence. (AUDIO: The Seeds of War)
