ICM's turn to trash Labour

Tomorrow's Guardian will have an ICM poll which shows Labour 13 points down on Conservative, a drop of 10 percentage points in a month:

Academic estimates suggest that on today's findings Labour would win 214 seats at a general election, down from 352, while the Conservatives could pick up a working majority with 355 seats, up around 160.

The Grey Budget didn't work, then. Time to sex things up?
