Shares in Liam Fox fell today as the rating agency, David Cameron, downgraded his confidence from "absolute and unequivocal support" to "total confidence" -two rating points down.
This is the second time in recent months that Cameron has had to downgrade a political partner -when he changed the rating of Andy Coulson from "close personal friend" to "someone I met once at a conference".
Liam Fox's downgrading immediately led some investors to sell off their stocks in Fox, although it did not lead to pick up in other politician's stock market values -Ed Milliband's value is still trading below its initial selling price.
The sudden change in rating has led some to question the role of the ratings agencies -and whether they have too much power. It was only two years ago, after all, that Cameron expressed strong support for Nick Clegg, only for him to vanish, causing all investors in Clegg to lose their money.
