Electoral Calculus says Labour doing better

From the Electoral Calculus website:

Recent polls still show a very strong Conservative lead over Labour, but one which
is slightly reduced from last month. Populus (Times) has 13% (down from 20%),
YouGov (Sunday Times) has 22% (up from 18%), ComRes (Independent on Sunday) has 21% (unchanged), ICM (Guardian) sees 15% (down from 20%), and Ipsos-MORI has 20% (up from 17%).

Overall the Conservative lead is 18% which is 1% lower than June. The prediction also includes the results of the recent YouGov poll in Scotland showing the SNP 4% ahead of Labour. As is our standard practice, we do not include the results of by-elections in the prediction because they are not a good predictor of subsequent general elections.

The current prediction is that the Conservatives will have a majority of 160 seats,
winning 405 seats (-1 seat since 28 Jun 2008).

Not really going to send Gordon on holiday with a spring to his step.
