It is now 20 years since the only occasion when a British minister, Angela Browning, resigned because she could no longer tolerate being told by her officials, whenever she proposed a sensible policy on some issue, “Oh no, minister, we can’t do that because it would be against European policy.” Vast numbers of our civil servants have grown up in a world where they have never had to think for themselves what might actually be the best policy for Britain, because such decisions have all been outsourced to a higher supranational level.
