Welensky considered a federal unilateral declaration of independence when the new Northern Rhodesian constitution appeared likely to grant an African majority in its parliament. Determined at one point to prevent changes, Welensky was convinced that if he refused, the British would use military force to remove his government. Believing that preparations were being made for an invasion from Kenya, he discussed the federation's ability to repel an attack with his defence chiefs and plans were set in motion. In the end, the idea of a British invasion was one of many options considered, and did not make it past cabinet discussion.
