Time Lord 1 (The Deadly Assassin)

A very old Time Lord was once changing into his robes of state when the Fourth Doctor stole his cloak in order to gain access to the Panopticon. This Time Lord told one of his contemporaries that he had witnessed the inauguration of Pandak III. He grumbled that more recent Lord Presidents didn't have the same staying power as Pandak, who reigned for 900 years.

Later, he gave evidence at the Doctor's trial that he saw the Doctor running to the Panopticon balcony just before the President's assassination. (DW: The Deadly Assassin)
