BTW. Just to put things in perspective this is a summary of the actual gains and losses

Labour +79
Conservative -24
Lib Dem +75
Green +8
UKIP -123
Other -5

It is difficult to tell the actual shift because of the massive loss for UKIP. Assuming the Torys (AKA BlueKIP) picked up most of those then the Tory loss becomes even more significant. Regardless of that, no matter how you spin it, Labour gained 79 seats while the Tories lost 24.
