Harold Macmillan famously cared little for the Arctic Monkeys.
In an interview with John Humphries on the Today programme yesterday, the Prime Minister found it necessary to defend himself from the suggestion that he was spending too much time with his family.
It prompted Max Atkinson to ask an excellent question: are parents of young children fit to run the country?
It's a simple fact that being the parent of young children - if it's done right - requires a great deal of time and effort. The sleep deprivation alone is famously punishing. Then there's, well, everything else. It seems common sense to conclude that the people having to deal with such demanding and stroppy bosses at home can't be doing their day jobs as well as they would otherwise.
In most cases, this temporary productivity decline is, from the point of view of society, a small price to pay. We accept that people who may be less effective in their jobs for a few years should nonetheless keep them, because we want a society as full of stable, happy families as possible. And those people may go on to be even better at their jobs when they come out the other side.
But Prime Ministers are a special case. They are only in the job for a few years (around ten at most). It's not just any job either - it's the job upon which, to some extent, all of our futures depend. It is also an unusually intense and demanding role (again - if it's done right). Would it not be sensible to appoint people to this position who had every chance of working at full capacity?
As Max suggests, this is one part of a larger issue, which is whether we made a sensible turn when we decided that we didn't want fuddy-duddy old grey hairs like Harold Macmillan in the top job, but young, dynamic and thrusting types - people who listened to the Arctic Monkeys (in Gordon Brown's day) and brought young families into Downing Street. Family aside, it's pretty clear that Cameron, like Blair before him in his first term, is suffering from his relative inexperience.
Maybe it's time to go grey again. As the UK population ages, it will be interesting to see if the age of our leaders moves in tandem. My vote is for Alistair Darling.
