As with the transfer of "Royalist" to the RNZN, the transfer of "Diadem" to Pakistan was controversial over the high cost of the refit. "Royalist" and "Diadem" were complex warships even as built in 1944. After refit and rewiring in 1956 they could never be more updated and had to be kept running with 200 men aboard even for short periods in reserve and refit; difficult for small navies such as the RNZN. In March 1953 "Royalist" had started a three year major reconstruction The "facelift' (new superstructure and electronics, but old engines) of "Royalist" was announced to start a large "Dido"/"Bellona" update programme. However the new PM, Churchill, favoured the RAF and the 1952 Navy Estimates was reduced.
