David Lloyd George
From Tardis Wiki, the free Doctor Who reference
David Lloyd George was a Human from the United Kingdom during the early 20th century. During that time period, he became the Prime Minister of Great Britain. The Ninth incarnation of the Doctor once said that Lloyd George used to drink him under the table at one point in his career, though it is unknown whether he was Prime Minster at that time.
