Vince Cable leapfogs William Hague back to the top of the of the PPI this month, presumably for his performance on Northern Rock. He's the only politician to score more than 6 out of 10. Harriet Harman remains rooted at the bottom, where she has been ever since I started doing this. For unfathomable reasons David Miliband and Ed Davey are the biggest climbers, while Jack Straw and James Purnell have experienced sharp falls. George Osborne and Andrew Lansley are also notable for their declines. Gordon Brown continues his steady improvement. Only 10 out of 42 politicians managed to do improve on their January scores, compared to 12 last month. We'll know when the state of British politics is on the up when that number reaches 22.
