I don't want to split hairs here, but I did not mention the Nene. The engines were Derwents, which is what the Klimov was derived from. But the point still stands. The technology was the same as led to the Mig-15.
And two more points.
Britain was in such a depression following the war that wartime assistance lasted into the Fifties, in the form of food, gasoline and housing stamps; that mass emigration occured in the middle class to SA, NZ, Canada and Asian countries. The Government, under whatever party, was forced to either increase taxation, decrease the national debt, or both.
Britain sought to sell the Comet overseas, which would have given axial turbofan technology (Avon), ultimately to the USSR, but were blocked from doing so.
