Thank goodness one constituency, at least, is alert to the danger that the general election could lead to a referendum that might take the UK out of the European Union. It is the City’s top concern about the election, according to the survey Financial News published on April 20.

And the fears of the City and business - the impact on trade, the London financial centre and the economy - will cut little ice with a wider public exposed to an onslaught of political posturing and toxic press propaganda.
