So, now we know what you need to be the most powerful woman in the world. It's really very simple. What you need to be is a wife.
That's a wife not in the sense that Gordon Brown needed to be a husband, in order to show that he had, on at least a handful of occasions, managed to swap endogenous growth theory for sexual intercourse, and also, of course, that he wasn't gay, which ought to be fine but which, judging by the number of politicians who have tried to hide it when they are, seems not to be. No, it's a wife in the sense of that's who you are, that's how you're defined, and that, in the end, is your job.
Michelle Obama, it's true, happens be married to the most powerful man in the world. But she was married to him last year, when Forbes magazine rated her the 40th most powerful woman in the world. She doesn't, it's fair to say, shape the foreign policy of the world's only superpower; she doesn't run the world's fifth biggest economy; she doesn't even host the world's most successful talk show. But she beats the women who do to the number one slot, because, according to the executive managing editor of Forbes Woman, this year's list is "weighted more towards media attention and social influence." And Michelle Obama, it's clear, has gained more, and better, media attention since she became less strident and more -- well, wifely.
The world has almost forgotten the fistbumps, and the lukewarm statements of national pride (both of which were clear indications of incipient terrorism). What it sees instead is a tall, slim, coiffed, buffed, super-elegant woman with a neat helmet of reassuringly Western-looking hair, and such magnificent arms that you feel that all future statues of multi-armed goddesses should be modelled on them. It sees a woman who's filmed digging vegetables in the organic garden she has created, and telling the nation that overeating makes you fat. It sees a woman who can make or break a career by the choice of her frock.
You just can't underestimate the power of a frock. There was a time when politicians' wives just had to look neat and unobtrusive. Nowadays, they can't set a stilettoed foot out of the door without having their entire outfit subjected to a rigorous taxonomy. It started here, I think, with Cherie Blair, whose fashion faux pas were almost as frequent as her verbal ones and contributed to memorable moments like the one where her ex-nude-model "lifestyle guru" was photographed showing her that lipstick goes on lips.
Sarah Brown, who gave up her job when she married her high-maintenance husband, and who, like Michelle, brought home-grown veg to the corridors of power (and who also, like Michelle, gave a he's-very-irritating-but-he's-my-hero speech at a strategic moment, perhaps not realising that it tends to work rather better with someone who's perceived as a hero than with someone who's perceived as very irritating), arrived in Downing Street looking a bit frumpy and a bit dumpy, but left looking really rather gorgeous. In the meantime, she had acquired a supermodel as a new best friend, and a wardrobe of designer dresses. Because suddenly, it seemed, if you were on the left you had to be a patron of a heartwarming international charity called "British fashion" and you had to look as though your political role models didn't include Shirley Williams.
If you're on the right, it's trickier. If, for example, you're someone who's never been the least bit interested in politics, but happen to be married to someone who's always quite fancied being prime minister, and you get paid nearly three times a prime minister's salary for working for a stationery company, and you're naturally very pretty and slender, and look good in pretty much anything, then you'll make sure that you're photographed in clothes from shops you didn't even know existed, shops where you don't even necessarily know the name of the person who designed your frock! But it doesn't matter, because it's all great fun, and your husband says that it's important to look as though you're "in touch" with ordinary people, though the ordinary people you've seen on those ghastly staycations you have to do for the cameras all seem to be wearing leggings which, from the size of them, they probably shouldn't.
And so, at the conference where your husband talks about becoming prime minister, you wear a dress from M&S (which everyone thought cost £65 but which, in fact, they had to make specially) and at the conference where your husband actually is Prime Minister, you wear a dress that costs £749, which is a lot less than one of the handbags you designed, because, well, because he's Prime Minister and you can't go on pretending to be a prole for ever.
The main thing to remember if you're a leader's wife is that you need to look good, but not too good. You want the men to fancy you and the women to think they'd like to look like you, not, à la Carla, that they hate your guts. You need to look as though you're interested in things like dresses, shoes, handbags, vegetables, cooking, charity and health. And you need to look as though your husband is your hero and you are his helpmate. Which means that if you have a job, unless it's something like a "creative director," you should probably give it up.
If this is the new politics, then, as David Cameron said, when Neil Kinnock boasted that he'd got his "party back," you can keep it.
