It is a reminder that, while concentrating on the vital question of restoring British independence and democratic accountability, the Leave campaign must talk more about how Brexit will actually help business.

So I was glad to receive a superb research paper by Dr Savvas Savouri of asset managers Toscafund, echoing a thought becoming more widespread in the Square Mile as big business, like almost everything else, starts to show a refreshing lack of unanimity about our European future: a paper that says, in these words, “Britain will be a better place for leaving the European Union.” It has been much discussed in City circles, but what is happening to our steel industry compels me to give it a wider audience.
