Queen Elizabeth II (that should also be Kittigate's answer, Canada isn't a republic either). John Gorton was Prime Minister in 1969, having succeeded to the leadership the previous year after the disappearance and presumed death by drowning of Harold Holt.
Both Nixon (Jan-Aug 9 1974) and Ford(Aug 9 -Dec 31 1974) were President that year. Ford was President when I was born.
