And Boris was asked by Paxman, on Newsnight, "What is the price of a pint [sic] of milk?" and did not know, eschewing the point that nobody can buy a pint of milk in a shop nowadays. He asked Paxman the price of a loaf; Paxman replied that he was not standing for office. Boris guessed 89 p for the milk, was told it was 'half that' and countered that he was thinking of the bigger container, semble, a litre. He may have been right for a litre. Was he?
Boris's point was that he didn't buy milk himself, but anyway the question was not relevant. All that he really needs to be aware of is the trend and rate of food price inflation and the cost of living, not the price of individual items in a food basket.
All that this favourite question of Mrs Thatcher's revealed was a) Paxman has his milk delivered, apparently and b) neither man does the shopping regularly and, if they do, they don't count the pennies. Both are men who work and also earn substantial sums, so neither revelation is a surprise but, rather, is to be expected. And we shouldn't expect anything else of them.
