Westminster gossip-mongers say there will much amusement at Caroline Flint's private office following her unintentional revelations that the cabinet were predicting a big downtown in the housing market.
Snappers had managed to capture all the gory details because she was carrying a see-through polythene file under her arms on the way to Downing Street.
What they wouldn't have known is just a few days before an angry Flint had created a scene in her private office, demanding they replace the not-so-transparent buff Whitehall folders with the flimsier see-through versions.
I bet she wishes now she had kept her mouth shut.
