Aldrig hört talas om detta, men det verkar som ekonomiska intressen vägde tungt:
Citat:
Having banned interracial marriage under the apartheid system, South Africa's government opposed having an interracial couple ruling just across their northern border. As Bechuanaland was then a British protectorate (not a colony), the South African government immediately exerted pressure on the UK to have Khama removed from his chieftainship. Britain’s Labour government, then heavily in debt from World War II, could not afford to lose cheap South African gold and uranium supplies. They also feared that South Africa might take more direct action against Bechuanaland, either economic sanctions or a military incursion.
The British government conducted a parliamentary enquiry into Khama’s fitness for the chieftainship. Although the investigation reported that he was eminently fit to rule the Bamangwato, "but for his unfortunate marriage", the government ordered that the report be suppressed (it would remain so for thirty years). It exiled Khama and his wife from Bechuanaland in 1951.
En riktigt osnygg historia med den nedtystade utredningen, men imperiepolitiken var sällan vacker. Det sägs inget om Churchills roll, men han var i själ och hjärta en ärkeimperialist. Dock fullt möjligt att scenen med honom är påhittad (manusförfattare är ofta extremt fräcka) eller att han helt enkelt gav efter för andra.
