Louise Mensch – darling of the twitterati and media doyenne. After well deserved praise, even by Labour bloggers, for how she handled potential media revelations about her past, she has become something of a Westminster village heroine.

Already there is chatter about her as future leadership material.

But she combines three qualities which are terminal for new MPs – independent profile, past baggage and a boldness verging on the reckless. Louise Mensch is more likely to crash and burn than become Tory PM.

As a multi-million selling author, Louise Mensch was already well known before becoming an MP. She had money, fans and journalists eager to seek her out.

The House of Commons is like school. A new kid with a reputation breeds resentment amongst the less blessed – both amongst the new intake but particularly from the older hands.

Disparaging asides about la Mensch are already doing the rounds in the tea room and the bars amongst her colleagues.

Last week, one of her female colleagues was seen to roll her eyes at her mention and hiss ‘Louise bloody Mensch’.  The whips are mistrusting and she is building up the one thing that newbies must avoid – enemies on her own side.

As someone with a past, the David Jones e-mail is just the start. Mensch was a press officer at EMI at the height of the “fruit and flowers” years.  So called because of the euphemistic line item in the budget, which was cover for £200,000 a year allegedly spent on other ingredients of the rock and roll “lifestyle”. In those days, EMI was a party company.

There will be lots more to come.

Her current line, a variant on George W Bush’s “when I was young and reckless I was young and reckless” is fine to a point, but its purpose is to box off debate on past misdemeanours. It begins to break down if there is a stream of new revelations.

Inevitably, given her admission, there will be further questions about when she changed her lifestyle. If Mensch has been a paragon of virtue since her twenties, she will be fine, but as a celebrity author in her thirties, the temptations would have been more, not less.

And then there’s her judgement.

On the plus side, her boldness in pressing News International on the culture select committee is commendable. But the self-confidence that led her, as a new MP, to challenge the Murdochs also meant she made those ridiculous charges about Piers Morgan without bothering to check the facts.

Success in politics builds slowly. The stars that shine the brightest, earliest, often burn out.

At the height of the expenses crisis, David Cameron made lots of noises about wanting candidates from different backgrounds that had been successful before politics. That were more independent and brought new experiences into the House of Commons.

Careful what you wish for, David.
