The lunchtime news had someone banging on about how we have a massive defence budget yet it is used as a kind of industrial subsidy. We need to decide whether the cash is for buying kit or subsidising skilled workers in marginal constituencies. Now the obvious thing is to have a rule, "Only buy British if it is the best". But that's b*llocks, because of course you just know over any timeframe we will slide into buying the same stuff we always buy - politicians want to be good, just not quite yet. The only solution is a self-denying ordinance (pardon the near pun). Never buy British, on the assumption that we should only be buying British 10% of the time anyway. A 10% smaller arms industry is a price worth paying if it means we always buy the best. And if our wonderful arms industry - which supposedly produces the best anyway - ends up (say) 90% smaller, what does that tell us about their claim to be world class?
