Hard sums

‘Choice’ is a word that is used liberally in Conservative thinking — whether it be about schools, hospitals or consumer goods. It is when consumers have choice, goes the argument, that providers of goods and services are forced to up their game. Choice brings diversity, inspiring new ideas and allowing for their success. It is not clear that the same rule applies to Conservative leadership elections.

Never before have Conservative MPs been presented with such a broad array of candidates. Ten made it to the first ballot, rather than the more usual four or five. It is hard to argue that the quality of the contest has improved as a result. On two of the most substantial issues — Brexit and the economy — there is a worrying paucity of ideas.

Boris Johnson, Sajid Javid and Dominic Raab all want to use the threat of no deal to extract a better deal from the EU.
