It's John Diefenbaker day in Ottawa. The prime minister has just returned from London, England, where he stood up to apartheid South Africa. The racist state was applying to be re-admitted to the British Commonwealth after becoming a republic. Diefenbaker proposed that the country could only be welcomed back into the fold if it joined other states in condemning apartheid in principle. South Africa withdrew its application, we see in this CBC Television clip. Everyone in Ottawa is eager to hear about the showdown. After briefing a packed House of Commons, Diefenbaker brings the annual meeting of the Conservative party to life. He tells his party that he fervently hopes South Africa will change its ways. "There will always be a light in the Commonwealth window."
