Winston Churchill

Winston Churchill was Prime Minister of Great Britain during World War II.

Biography
Churchill met the Doctor and Peri during two periods of his life, first in 1899, when he served as a war correspondent and later in the 1930s. (PDA: Players) The Doctor met with him again in 1944. (PDA: The Shadow in the Glass)

At some unknown stage in his life, Momus abducted Churchill from his own time to Belgium in 800 CE. (WC: The Lonely Computer).

At some point in 1940 or 1941 he called the Doctor's TARDIS as a Dalek moved towards him. (DW: The Beast Below) When the Doctor got there a month later, in 1941, it was revealed that the Daleks had somehow managed to convince Churchill that they were a manmade superweapon (which Churchill named 'ironsides') which he could use to win the war (DW: Victory of the Daleks).

Other Timelines
In an alternate timeline in which Germany won World War II, Churchill was executed as a war criminal. (NA: Timewyrm: Exodus)
