Robert Peel

Sir Robert Peel was a former Home Secretary of the United Kingdom. Gwen Cooper named him as a famous police officer, to which Jack Harkness replied that she was wrong - he was a Home Secretary. (PROSE: Another Life)

The Eighth Doctor told Liv Chenka that he was one of Sir Robert's first peelers. (AUDIO: The Red Lady)

Behind the scenes
In the real world, Robert Peel served twice as Home Secretary. He also served twice as Prime Minister of the United Kingdom. These real world facts, however, have yet to be confirmed within the DWU.
