Just stepped off the Tube to read that Kitty Ussher - the Treasury minister - has resigned from the Government over her expenses. The Telegraph writes that "further disclosures" about her claims are "due to be published" by them - so I imagine that could have been the direct cause. All in all, a reminder that this scandal is still rumbling on, claiming scalps, and that the fragmentation of Brown's government didn't end with the Cabinet reshuffle.
P.S. Read Martin's take on Ussher's departure here.
