In the 50s, Nicholas Monsarrat, of “Cruel Sea” fame, wrote a novel entitled “The Tribe That Lost Its Head.” That was prophetic. He might have been writing an account of the past few months in British politics. In a world beset by difficulty and danger, we have been arguing about cakes and garden parties. It is time to brush that aside and return to seriousness so that we can use the word “party” without giggling in the background. Our Party must lead that return and thereby regain the confidence of the British people.
