"Churchill's Secret" is based on Jonathan Smith's recently published book, "The Churchill Secret: KBO", set during the summer of 1953 when the then-peacetime prime minister had a stroke, which was kept secret from the world, reported Guardian Online.
"Churchill's Secret is the extraordinary and compelling story of how one of our country's most famous political figures battled back from life-threatening illness to hold on to power," said Steve November, ITV director of drama.
